Subject: [PATCH 001/618] kmemleak: Do not use off-slab management with
SLAB_NOLEAKTRACE
With the slab allocator, if off-slab management is enabled for the
kmem_caches used by kmemleak, it leads to recursive calls into
kmemleak_alloc(). Off-slab management can be triggered by other config
options increasing the slab size, e.g. DEBUG_PAGEALLOC.

Subject: [PATCH 006/618] kmemleak: Reduce the false positives by checking for
modified objects
If an object was modified since it was previously suspected as leak, do
not report it. The modification check is done by calculating the
checksum (CRC32) of such object.
Several false positives are caused by objects being removed from linked
lists (e.g. allocation pools) and temporarily breaking the reference
chain since kmemleak runs concurrently with such list mutation
primitives.

Subject: [PATCH 008/618] ocfs2: Find proper end cpos for a leaf refcount
block.
ocfs2 refcount tree is stored as an extent tree while
the leaf ocfs2_refcount_rec points to a refcount block.
The following step can trip a kernel panic.
mkfs.ocfs2 -b 512 -C 1M --fs-features=refcount $DEVICE
mount -t ocfs2 $DEVICE $MNT_DIR
FILE_NAME=$RANDOM
FILE_NAME_1=$RANDOM
FILE_REF="${FILE_NAME}_ref"
FILE_REF_1="${FILE_NAME}_ref_1"
for((i=0;i<305;i++))
do
# /mnt/1048576 is a file with 1048576 sizes.
cat /mnt/1048576 >> $MNT_DIR/$FILE_NAME
cat /mnt/1048576 >> $MNT_DIR/$FILE_NAME_1
done
for((i=0;i<3;i++))
do

done
reflink $MNT_DIR/$FILE_NAME $MNT_DIR/$FILE_REF
# write_f is a program which will write some bytes to a file at offset.
# write_f -f file_name -l offset -w write_bytes.
./write_f -f $MNT_DIR/$FILE_REF -l $[310*1048576] -w 4096

#kernel panic here.
The reason is that if the ocfs2_extent_rec is the last record
in a leaf extent block, the old solution fails to find the
suitable end cpos. So this patch try to walk through the b-tree,
find the next sub root and get the c_pos the next sub-tree starts
from.
btw, I have runned tristan's test case against the patched kernel
for several days and this type of kernel panic never happens again.

Subject: [PATCH 011/618] powerpc/fsl_pci: Fix P2P bridge handling for MPC83xx
PCIe controllers
It appears that we wrongly calculate dev_base for type1 config cycles.
The thing is: we shouldn't subtract hose->first_busno because PCI core
sets PCI primary, secondary and subordinate bus numbers, and PCIe
controller actually takes the registers into account. So we should use
just bus->number.
Also, according to MPC8315 reference manual, primary bus number should
always remain 0. We have PPC_INDIRECT_TYPE_SURPRESS_PRIMARY_BUS quirk
in indirect_pci.c, but since 83xx is somewhat special, it doesn't use
indirect_pci.c routines, so we have to implement the quirk specifically
for 83xx PCIe controllers.

+* OpenPIC and its interrupt numbers on Freescale's e500/e600 cores
+
+The OpenPIC specification does not specify which interrupt source has to
+become which interrupt number. This is up to the software implementation
+of the interrupt controller. The only requirement is that every
+interrupt source has to have an unique interrupt number / vector number.
+To accomplish this the current implementation assigns the number zero to
+the first source, the number one to the second source and so on until
+all interrupt sources have their unique number.
+Usually the assigned vector number equals the interrupt number mentioned
+in the documentation for a given core / CPU. This is however not true
+for the e500 cores (MPC85XX CPUs) where the documentation distinguishes
+between internal and external interrupt sources and starts counting at
+zero for both of them.
+
+So what to write for external interrupt source X or internal interrupt
+source Y into the device tree? Here is an example:
+
+The memory map for the interrupt controller in the MPC8544[0] shows,
+that the first interrupt source starts at 0x5_0000 (PIC Register Address
+Map-Interrupt Source Configuration Registers). This source becomes the
+number zero therefore:
+ External interrupt 0 = interrupt number 0
+ External interrupt 1 = interrupt number 1
+ External interrupt 2 = interrupt number 2
+ ...
+Every interrupt number allocates 0x20 bytes register space. So to get
+its number it is sufficient to shift the lower 16bits to right by five.
+So for the external interrupt 10 we have:
+ 0x0140 >> 5 = 10
+
+After the external sources, the internal sources follow. The in core I2C
+controller on the MPC8544 for instance has the internal source number
+27. Oo obtain its interrupt number we take the lower 16bits of its memory
+address (0x5_0560) and shift it right:
+ 0x0560 >> 5 = 43
+
+Therefore the I2C device node for the MPC8544 CPU has to have the
+interrupt number 43 specified in the device tree.

In testing 2.6.31 on one of our ia64 platforms I've encountered a hang
due to the driver using hardware ATEs which are a limited resource.
This is because the driver does not set the dma consistent mask to
64 bits.

Subject: [PATCH 021/618] [SCSI] pmcraid: support SMI-S object model of storage
pool
PMC-Sierra mgmt application uses SMI-S model. According to SMI-S, the
object model exposed by the SMI-S provider should show an StoragePool
which contains member disks of a RAID Virtual disk and StorageVolume
based on the StoragePool. But according to SMI-S, there is a possibility
where StoragePool is created but StorageVolume is not yet created. To
satisfy this scenario, we are trying a hidden RAID Virtual disk. The
hidden RAID virtual disk will not be exposed to OS. Once a StorageVolume
is created for this RAID virtual disk it is exposed.

This patch allows for future addition of various async messages
from the chip. This ensures that the driver won't hit a BUG_ON if
the Firmware used is newer than inbox driver and so is using
latest async messages.

Subject: [PATCH 024/618] [SCSI] st: fix mdata->page_order handling
dio transfer always resets mdata->page_order to zero. It breaks
high-order pages previously allocated for non-dio transfer.
This patches adds reserved_page_order to st_buffer structure to save
page order for non-dio transfer.
http://bugzilla.kernel.org/show_bug.cgi?id=14563
When enlarge_buffer() allocates 524288 from 0, st uses six-order page
allocation. So mdata->page_order is 6 and frp_seg is 2.
After that, if st uses dio, sgl_map_user_pages() sets
mdata->page_order to 0 for st_do_scsi(). After that, when we call
normalize_buffer(), it frees only free frp_seg * PAGE_SIZE (2 * 4096)
though we should free frp_seg * PAGE_SIZE << 6 (2 * 4096 << 6). So we
see buffer_size is set to 516096 (524288 - 8192).

enclosure_status array
Based on patch originally by Jeff Mahoney <jeffm@suse.com>
enclosure_status is expected to be a NULL terminated array of strings
but isn't actually NULL terminated. When writing an invalid value to
/sys/class/enclosure/.../.../status, it goes off the end of the array
and Oopses.
Fix by making the assumption true and adding NULL at the end.

Subject: [PATCH 028/618] [SCSI] megaraid_sas: make driver PCI legacy I/O port
free driver
On the large servers, I/O port resource may not be assigned to all
the PCI devices since it is limited (to 64KB on Intel Architecture[1])
and it may also be fragmented (I/O base register of PCI-to-PCI bridge
will usually be aligned to a 4KB boundary[2]).
If no I/O port resource is assigned to devices, those devices do not
work.
[1] Some machines support 64KB I/O port space per PCI segment.
[2] Some P2P bridges support optional 1KB aligned I/O base.
Therefore, I made a patch for MegaRAID SAS driver to make PCI legacy
I/O port free. I have also tested the patch and it had no problem.
The way to make PCI legacy I/O port free is the same as Fusion-MPT
driver's and it has been merged into 2.6.30.4.
This has already been fixed in e1000 and lpfc.
As a result of the above, the driver can handle its device even when
there are a huge number of PCI devices being used on the system and no
I/O port region assigned to the device.

Subject: [PATCH 029/618] [SCSI] libosd: Fix blk_put_request locking again
So libosd has decided to sacrifice some code simplicity for the sake of
a clean API. One of these things is the possibility for users to call
osd_end_request, in any condition at any state. This opens up some
problems with calling blk_put_request when out-side of the completion
callback but calling __blk_put_request when detecting a from-completion
state.
The current hack was working just fine until exofs decided to operate on
all devices in parallel and wait for the sum of the requests, before
deallocating all osd-requests at once. There are two new possible cases
1. All request in a group are deallocated as part of the last request's
async-done, request_queue is locked.
2. All request in a group where executed asynchronously, but
de-allocation was delayed to after the async-done, in the context of
another thread. Async execution but request_queue is not locked.
The solution I chose was to separate the deallocation of the osd_request
which has the information users need, from the deallocation of the
internal(2) requests which impose the locking problem. The internal
block-requests are freed unconditionally inside the async-done-callback,
when we know the queue is always locked. If at osd_end_request time we
still have a bock-request, then we know it did not come from within an
async-done-callback and we can call the regular blk_put_request.
The internal requests were used for carrying error information after
execution. This information is now copied to osd_request members for
later analysis by user code.
The external API and behaviour was unchanged, except now it really
supports what was previously advertised.

So, it appears that qla2xxx dpc thread is moving forward before the
scsi host has been completely added.
This patch moves the setting of the init_done (and online) flag to
after the call to scsi_add_host() to hold off the dpc thread.
Found via large lun count testing using 2.6.31.

resources.
Powerpc 44x uses 36 bit real address while the real address defined in
MPT Fusion driver is of type 32 bit. This causes ioremap to fail and
driver fails to initialize. This fix changes the data types
representing the real address from unsigned long 32-bit types to
resource_size_t which is 64-bit. The driver has been tested, the disks
get discovered correctly and can do IO.

Subject: [PATCH 036/618] [SCSI] ipr: fix EEH recovery
After commits c82f63e411f1b58427c103bd95af2863b1c96dd1 (PCI: check saved
state before restore) and 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff (PCI:
Clear saved_state after the state has been restored) PCI drivers are
prevented from restoring the device standard configuration registers
twice in a row. These changes introduced a regression on ipr EEH
recovery.
The ipr device driver saves the PCI state only during the device probe
and restores it on ipr_reset_restore_cfg_space() during IOA resets. This
behavior is causing the EEH recovery to fail after the second error
detected, since the registers are not being restored.
One possible solution would be saving the registers after restoring
them. The problem with this approach is that while recovering from an
EEH error if pci_save_state() results in an EEH error, the adapter/slot
will be reset, and end up back in ipr_reset_restore_cfg_space(), but it
won't have a valid saved state to restore, so pci_restore_state() will
fail.
The following patch introduces a workaround for this problem, hacking
around the PCI API by setting pdev->state_saved = true before we do the
restore. It fixes the EEH regression and prevents that we hit another
EEH error during EEH recovery.
[jejb: fix is a hack ... Jesse and Rafael will fix properly]

Subject: [PATCH 038/618] [SCSI] bnx2i: Adjust sq_size module parametr to power
of 2 only if a non-zero value is specified
This issue was discovered during 10G iscsi testing
Default value of 'sq_size' module parameter is '0' which means driver
should use predefined SQ queue size when setting up iscsi connection.
roundup_pow_of_two(0) results in '1' and forces driver to setup
connections with send queue size of '1' and results in lower
performance as well

Due to typo error driver was failing TMF Abort Task request when
ctask->sc != NULL. Fixed code to fail TMF ABORT Task request only when
ctask->sc == NULL. Clear age component (19 most significant bits) of
reference ITT carried in iSCSI TMF PDU. Age component is internal to
initiator side and only lower bits of ITT as defined by ISCSI_ITT_MASK
is is sent on wire. Retrieve LUN directly from the ref_sc and update
SQ wqe as per chip HSI (Host Software Interface) specification

Subject: [PATCH 044/618] [SCSI] pm8001: Fix for sata io circular lock
dependency.
This patch fix for sata IO circular lock dependency. When we call task_done
for SATA IO, we have got pm8001_ha->lock ,and in sas_ata_task_done, it will
get (dev->sata_dev.ap->lock. then cause circular lock dependency .So we
should drop pm8001_ha->lock when we call task_done for SATA task.

Subject: [PATCH 054/618] signal: Fix racy access to __task_cred in
kill_pid_info_as_uid()
kill_pid_info_as_uid() accesses __task_cred() without being in a RCU
read side critical section. tasklist_lock is not protecting that when
CONFIG_TREE_PREEMPT_RCU=y.
Convert the whole tasklist_lock section to rcu and use
lock_task_sighand to prevent the exit race.

Subject: [PATCH 055/618] signals: Fix more rcu assumptions
1) Remove the misleading comment in __sigqueue_alloc() which claims
that holding a spinlock is equivalent to rcu_read_lock().
2) Add a rcu_read_lock/unlock around the __task_cred() access
in __sigqueue_alloc()
This needs to be revisited to remove the remaining users of
read_lock(&tasklist_lock) but that's outside the scope of this patch.

Subject: [PATCH 056/618] sys: Fix missing rcu protection for __task_cred()
access
commit c69e8d9 (CRED: Use RCU to access another task's creds and to
release a task's own creds) added non rcu_read_lock() protected access
to task creds of the target task in set_prio_one().
The comment above the function says:
* - the caller must hold the RCU read lock
The calling code in sys_setpriority does read_lock(&tasklist_lock) but
not rcu_read_lock(). This works only when CONFIG_TREE_PREEMPT_RCU=n.
With CONFIG_TREE_PREEMPT_RCU=y the rcu_callbacks can run in the tick
interrupt when they see no read side critical section.
There is another instance of __task_cred() in sys_setpriority() itself
which is equally unprotected.
Wrap the whole code section into a rcu read side critical section to
fix this quick and dirty.
Will be revisited in course of the read_lock(&tasklist_lock) -> rcu
crusade.
Oleg noted further:
This also fixes another bug here. find_task_by_vpid() is not safe
without rcu_read_lock(). I do not mean it is not safe to use the
result, just find_pid_ns() by itself is not safe.
Usually tasklist gives enough protection, but if copy_process() fails
it calls free_pid() lockless and does call_rcu(delayed_put_pid().
This means, without rcu lock find_pid_ns() can't scan the hash table
safely.

Subject: [PATCH 057/618] powerpc/83xx/suspend: Clear deep_sleeping after
devices resume
Currently 83xx PMC driver clears deep_sleeping variable very early,
before devices are resumed. This makes fsl_deep_sleep() unusable in
drivers' resume() callback.
Sure, drivers can store fsl_deep_sleep() value on suspend and use
the stored value on resume. But a better solution is to postpone
clearing the deep_sleeping variable, i.e. move it into finish()
callback.

Subject: [PATCH 063/618] clockevents: Prevent clockevent_devices list
corruption on cpu hotplug
Xiaotian Feng triggered a list corruption in the clock events list on
CPU hotplug and debugged the root cause.
If a CPU registers more than one per cpu clock event device, then only
the active clock event device is removed on CPU_DEAD. The unused
devices are kept in the clock events device list.
On CPU up the clock event devices are registered again, which means
that we list_add an already enqueued list_head. That results in list
corruption.
Resolve this by removing all devices which are associated to the dead
CPU on CPU_DEAD.

Subject: [PATCH 067/618] kbuild: fix bzImage build for x86
As has been discussed previously (and Sam has been CC'ed), the fix
is still incorrect. It replaces "echo -ne" with "/bin/echo -ne",
but neither of the two are guaranteed to support the necessary
arguments and necessary (hexadecimal) escape sequences. What should
be used here is printf(1). The trivial patch below (on top of these
kbuild changes) fixes this issue.

Subject: [PATCH 068/618] kbuild: search arch/$ARCH/include before include/
The namespace used in arch/$ARCH/include is different from
what is used in include/ except for the include/asm directory.
This patch gives the arch/$ARCH/include/asm directory priority
over include/asm.
When we add asm-offsets.h to arch/$ARCH/include/asm/ this
patch makes sure we pick up the arch specific version
and not the one we have in include/asm.
The situation with an asm-offsets.h file located in
both include/asm _and_ arch/$ARCH/include/asm will happen
when we move more files over to include/generated.
This happens because in some cases it is not practical
to rename all users so we simply add a file
in arch/$ARCH/include/asm that includes the generated version.
This is the solution we use for asm-offsets.h as an example.

Subject: [PATCH 071/618] kbuild: move asm-offsets.h to include/generated
The simplest method was to add an extra asm-offsets.h
file in arch/$ARCH/include/asm that references the generated file.
We can now migrate the architectures one-by-one to reference
the generated file direct - and when done we can delete the
temporary arch/$ARCH/include/asm/asm-offsets.h file.

Subject: [PATCH 077/618] kbuild: drop include/asm
We no longer use this directory for generated files and
all architectures has moved their header files so no
symlink tricks are needed either.
Drop the symlink and drop the ARCH check.
If we really need to check that the SRCARCH has not changed
when we build a kernel we can add this check back - but then we will
find a more convenient way to store the info.

Subject: [PATCH 084/618] scripts/package: tar-pkg: use tar --owner=root
Use the --owner= and --group= options to make sure the entries in
the built tar file are owned by root. Without this change, a
careless sysadmin using the tar-pkg target can easily end up
installing a kernel that is writable by the unprivileged user
account used to build the kernel.
Test that these options are understood before using them so that
non-GNU versions of tar can still be used if the operator is
appropriately cautious.

Subject: [PATCH 085/618] scripts/package: add KBUILD_PKG_ROOTCMD variable
Let the deb-pkg target acquire (fake) root privileges before
running commands that need them. Without such privileges,
deb-pkg errors out because chown fails.
The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a
command to run other commands with possibly fake elevated
privileges. Since this is not needed for the tar-pkg and rpm-pkg
targets, it is only used by deb-pkg. If it is not defined, the
behavior is as before, and the user will have to rerun make as
root.
In other words, as a shortcut, instead of running 'make oldconfig &&
make && fakeroot -u make deb-pkg', one can use the single command
'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

Subject: [PATCH 086/618] scripts/package: deb-pkg: use fakeroot if available
Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or
becoming root oneself or it errors out. Unless already running
as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a
good default.
With this patch applied, you can run "make oldconfig deb-pkg" as
an ordinary user to build a binary package for an updated kernel
tree and it should just work.
fakeroot is too zealous by default in treating files as owned by
root. Its wrapped stat() sets st_uid and st_gid to 0 for all
files, which causes Git to go on a wild goose chase if
CONFIG_LOCALVERSION_AUTO is set, checking if any file's content
has changed along with its stat information. Avoid this by
telling fakeroot to use the actual owner and group for
preexisting files, by passing it the -u option.

Subject: [PATCH 088/618] kbuild: specify absolute paths for cscope
Cscope doesn't hadle relative paths when cscope.out is not in $PWD. Use
absolute paths when generating cscope.files, which seems to be the
recommended way to generate cscope.out, anyway (at least according to
cscope.sf.net). The speed and size differences are minimal, the only
drawback is that the database needs to be regenerated if the source
directory is moved.

Subject: [PATCH 089/618] unifdef: update to upstream revision 1.190
Fix handling of input files (e.g. with no newline at EOF) that could
make unifdef get into an unexpected state and call abort().
The new -B option compresses blank lines around a deleted section
so that blank lines around "paragraphs" of code don't get doubled.
The evaluator can now handle macros with arguments, and unbracketed
arguments to the "defined" operator.
Add myself to MAINTAINERS for unifdef.

Subject: [PATCH 091/618] genksyms: properly consider
EXPORT_UNUSED_SYMBOL{,_GPL}()
Despite being unused these should also get a CRC calculated.
Primarily I view this as a consistency thing. But I also think this is
one of the reasons why __crc_* need to be weak (which I think should be
avoided, and hence we should have the goal to eliminate this so that
failure to calculate a proper CRC for a symbol causes the build to fail).

Subject: [PATCH 092/618] kbuild: generate modules.builtin
To make it easier for module-init-tools and scripts like mkinitrd to
distinguish builtin and missing modules, install a modules.builtin file
listing all builtin modules. This is done by generating an additional
config file (tristate.conf) with tristate options set to uppercase 'Y'
or 'M'. If we source that config file, the builtin modules appear in
obj-Y.

c) no work gets scheduled for the remote work to fc_rport_work
After this point, shut/no-shut of the remote port did not cause the port
to get re-discovered. The port would move betwen DELETE and RESTART states,
but the event would always be STOP, no work would get scheduled to
fc_rport_work and the port would not get added to scsi_transport.
The problem is that rdata->event is not set to NONE after a port is
restarted. After this point, no more work gets scheduled for the remote port
since new work is scheduled only if rdata->event is non-NONE. So, the event
and state keep changing, but fc_rport_work does not get scheduled to actually
handle the event.
Here's a transition of states that explains the above observation:
) Port is first in READY State, event is NONE
2) RSCN on shut, port goes to DELETED, event is stop
3) Before fc_rport_work runs, RSCN on no-shut, port goes to RESTART, event is
still STOP
4) fc_rport_work gets scheduled, removes the port from transport, sees state
as RESTART, begins the PLOGI state machine, event remains as STOP (event NOT
changed to NONE, this is the bug)
5) Plogi state machine completes, port state goes to READY, event goes to
READY, but no work is scheduled since event was STOP (non-NONE) before.
Fc_rport_work is not scheduled, port remains in READY state, but is not added
to transport.
Things are broken at this point. Libfc rport is ready, but no transport rport
created.
6) now a shut causes port state to change to DELETE, event to change to STOP,
no work gets scheduled
7) no-shut causes port state to change to RESTART, event remains at STOP,
no work gets scheduled
(6) and (7) now get repeated everytime we do shut/no-shut. No way to get out
of this state. Fcc reset does not help too.
Only way to get out is to load/unload module.
Fix is to set rdata->event to NONE while processing the STOP/LOGO/FAILED
events, inside the discovery and rport locks.

Subject: [PATCH 097/618] [SCSI] libfc: reduce hold time on SCSI host lock
Introduce a new lock to protect the list of fc_fcp_pkt structs in libfc
instead of using the host lock. This reduces the contention of this heavily
used lock, and I see up to a 25% performance gain in CPU bound small I/O
tests when scaling out across multiple quad-core CPUs.
The big win is in removing the host lock from the completion path
completely, as it does not need to be held around the call to scsi_done.

Subject: [PATCH 098/618] [SCSI] fcoe, libfc: adds enable/disable for fcoe
interface
This is to allow fcoemon util to enable or disable a fcoe interface
according to DCB link state change.
Adds sysfs module param enable and disable for this and also
updates existing other module param description to be consistent
and more accurate since older description had double "fcoe" word
with less meaningful netdev reference to user space.
Adds code to ignore redundant fc_lport_enter_reset handling for a
already disabled fcoe interface by checking LPORT_ST_DISABLED
or LPORT_ST_LOGO states, this also prevents lport state transition
on link flap on a disabled interface.
Above changes required lport state transition to get out of
disabled or logo state on call to fc_fabric_login.

Subject: [PATCH 100/618] sched: Make wakeup side and atomic variants of
completion API irq safe
Alan Stern noticed that all the wakeup side (and atomic) variants of the
completion APIs should be irq safe, but the newly introduced
completion_done() and try_wait_for_completion() aren't. The use of the
irq unsafe variants in IRQ contexts can cause crashes/hangs.
Fix the problem by making them use spin_lock_irqsave() and
spin_lock_irqrestore().

Subject: [PATCH 103/618] ARM: cache-l2x0: make better use of background cache
handling
There's no point having the hardware support background operations
if we issue a cache operation, and then wait for it to complete
before calculating the address of the next operation. We gain no
advantage in the cache controller stalling the bus until completion.
What we should be doing is using the 'wait' time productively by
calculating the address of the next operation, and only then waiting
for the previous operation to complete. This means that cache
operations can occur in parallel with the CPU calculating the next
address.

Subject: [PATCH 104/618] ARM: 5848/1: kill flush_ioremap_region()
There is not enough users to warrant its existence, and it is actually
an obstacle to progress with the new DMA API which cannot cover this
case properly.
To keep backward compatibility, let's perform the necessary custom
cache maintenance locally in the only driver affected.

From 2c9b9c8490b60428fa2d1c64042f7c7caed93940 Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Thu, 26 Nov 2009 12:56:21 +0000
Subject: [PATCH 105/618] ARM: add size argument to __cpuc_flush_dcache_page
... and rename the function since it no longer operates on just
pages.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Subject: [PATCH 106/618] ARM: use flush_kernel_dcache_area() for dmabounce
After copying data from the bounce buffer to the real buffer, use
flush_kernel_dcache_page() to ensure that data is written back in
manner coherent with future userspace mappings.

Subject: [PATCH 107/618] sched: Use rcu in
sys_sched_getscheduler/sys_sched_getparam()
read_lock(&tasklist_lock) does not protect
sys_sched_getscheduler and sys_sched_getparam() against a
concurrent update of the policy or scheduler parameters as
do_sched_setscheduler() does not take the tasklist_lock. The
accessed integers can be retrieved w/o locking and are snapshots
anyway.
Using rcu_read_lock() to protect find_task_by_vpid() and prevent
the task struct from going away is not changing the above
situation.

Subject: [PATCH 108/618] sched: Use rcu in sched_get/set_affinity()
tasklist_lock is held read locked to protect the
find_task_by_vpid() call and to prevent the task going away.
sched_setaffinity acquires a task struct ref and drops tasklist
lock right away. The access to the cpus_allowed mask is
protected by rq->lock.
rcu_read_lock() provides the same protection here.

Subject: [PATCH 109/618] sched: Use rcu in sched_get_rr_param()
read_lock(&tasklist_lock) does not protect
sys_sched_get_rr_param() against a concurrent update of the
policy or scheduler parameters as do_sched_scheduler() does not
take the tasklist_lock.
The access to task->sched_class->get_rr_interval is protected by
task_rq_lock(task).
Use rcu_read_lock() to protect find_task_by_vpid() and prevent
the task struct from going away.

Subject: [PATCH 110/618] sched: Fix cpu_clock() in NMIs, on
!CONFIG_HAVE_UNSTABLE_SCHED_CLOCK
Relax stable-sched-clock architectures to not save/disable/restore
hardirqs in cpu_clock().
The background is that I was trying to resolve a sparc64 perf
issue when I discovered this problem.
On sparc64 I implement pseudo NMIs by simply running the kernel
at IRQ level 14 when local_irq_disable() is called, this allows
performance counter events to still come in at IRQ level 15.
This doesn't work if any code in an NMI handler does
local_irq_save() or local_irq_disable() since the "disable" will
kick us back to cpu IRQ level 14 thus letting NMIs back in and
we recurse.
The only path which that does that in the perf event IRQ
handling path is the code supporting frequency based events. It
uses cpu_clock().
cpu_clock() simply invokes sched_clock() with IRQs disabled.
And that's a fundamental bug all on it's own, particularly for
the HAVE_UNSTABLE_SCHED_CLOCK case. NMIs can thus get into the
sched_clock() code interrupting the local IRQ disable code
sections of it.
Furthermore, for the not-HAVE_UNSTABLE_SCHED_CLOCK case, the IRQ
disabling done by cpu_clock() is just pure overhead and
completely unnecessary.
So the core problem is that sched_clock() is not NMI safe, but
we are invoking it from NMI contexts in the perf events code
(via cpu_clock()).
A less important issue is the overhead of IRQ disabling when it
isn't necessary in cpu_clock().
CONFIG_HAVE_UNSTABLE_SCHED_CLOCK architectures are not
affected by this patch.

Subject: [PATCH 113/618] bzip2/lzma/gzip: pre-boot malloc doesn't return NULL
on failure
The trivial malloc implementation used in the pre-boot environment by the
decompressors returns a bad pointer on failure (falling through after
calling error). This is doubly wrong - the callers expect malloc to
return NULL on failure, second the error function is intended to be
used by the decompressors to propagate errors to *their* callers. The
decompressors have no access to any state set by the error function.

Subject: [PATCH 115/618] initramfs: add missing decompressor error check
The decompressors return error by calling a supplied error function, and/or
by returning an error return value. The initramfs code, however, fails to
check the exit code returned by the decompressor, and only checks the error
status set by calling the error function.
This patch adds a return code check and calls the error function.

register_chrdev() hardcodes registering 256 minors, presumably to
avoid breaking old drivers. However, we need to register enough
minors so that we have all possible CPUs.
checkpatch warns on this patch, but the patch is correct: NR_CPUS here
is a static *upper bound* on the *maximum CPU index* (not *number of
CPUs!*) and that is what we want.

Subject: [PATCH 118/618] Btrfs: Add btrfs_duplicate_item
btrfs_duplicate_item duplicates item with new key, guaranteeing
the source item and the new items are in the same tree leaf and
contiguous. It allows us to split file extent in place, without
using lock_extent to prevent bookend extent race.

Subject: [PATCH 122/618] drm/nouveau: use drm debug levels
- Use driver level (0x2) for NV_DEBUG instead of all levels
- Create a NV_DEBUG_KMS for KMS level (0x4) and use them in modesetting code
- Remove a few odd NV_TRACE calls and replace some of them with NV_DEBUG_KMS or
NV_INFO

From 054b93e444550a72aef17115363cdef253b9ee7c Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Tue, 15 Dec 2009 22:02:47 +1000
Subject: [PATCH 129/618] drm/nv40: implement ctxprog/state generation
The context programs are *very* simple compared to the ones used by
the binary driver. There's notes in nv40_grctx.c explaining most of
the things we don't implement. If we discover if/why any of it is
required further down the track, we'll handle it then.
The PGRAPH state generated for each chipset should match what NVIDIA
do almost exactly (there's a couple of exceptions). If someone has
a lot of time on their hands, they could figure out the mapping of
object/method to PGRAPH register and demagic the initial state a little,
it's not terribly important however.
At time of commit, confirmed to be working at least well enough for
accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46,
NV49, NV4A, NV4B and NV4E.
A module option has been added to force the use of external firmware
blobs if it becomes required.

+ * programs have this code, nor whether it's strictly necessary for
+ * correct operation. We'll implement additional handling if/when we
+ * discover it's necessary.
+ *
+ * - On context save, NVIDIA set 0x400314 bit 0 to 1 if the "3D state"
+ * flag is set, this gets saved into the context.
+ * - On context save, the context program for all cards load nsource
+ * into a flag register and check for ILLEGAL_MTHD. If it's set,
+ * opcode 0x60000d is called before resuming normal operation.
+ * - Some context programs check more conditions than the above. NV44
+ * checks: ((nsource & 0x0857) || (0x400718 & 0x0100) || (intr & 0x0001))
+ * and calls 0x60000d before resuming normal operation.
+ * - At the very beginning of NVIDIA's context programs, flag 9 is checked
+ * and if true 0x800001 is called with count=0, pos=0, the flag is cleared
+ * and then the ctxprog is aborted. It looks like a complicated NOP,
+ * its purpose is unknown.
+ * - In the section of code that loads the per-vs state, NVIDIA check
+ * flag 10. If it's set, they only transfer the small 0x300 byte block
+ * of state + the state for a single vs as opposed to the state for
+ * all vs units. It doesn't seem likely that it'll occur in normal
+ * operation, especially seeing as it appears NVIDIA may have screwed
+ * up the ctxprogs for some cards and have an invalid instruction
+ * rather than a cp_lsr(ctx, dwords_for_1_vs_unit) instruction.
+ * - There's a number of places where context offset 0 (where we place
+ * the PRAMIN offset of the context) is loaded into either 0x408000,
+ * 0x408004 or 0x408008. Not sure what's up there either.
+ * - The ctxprogs for some cards save 0x400a00 again during the cleanup
+ * path for auto-loadctx.

Subject: [PATCH 131/618] drm/nouveau: prevent all channel creation if accel
not available
Previously, if there was no firmware available, the DRM would just
disable channel creation from userspace, but still use a single
channel for its own purposes.
With a bit of care it should actually be possible to do this, due
to the DRM's very limited use of the engine. It currently doesn't
work correctly however, resulting in corrupted fbcon and hangs on
a number of cards.

Subject: [PATCH 137/618] leds: LED driver for Intel NAS SS4200 series (v5)
This code is based on a driver that came in the "Open-source
and GPL components" download here:
http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Server+Products&ProductLine=Intel%C2%AE+Storage+Systems&ProductProduct=Intel%C2%AE+Entry+Storage+System+SS4200-E&OSVersion=OS+Independent
It was in a file called nasgpio.c inside of a second zip file
called SS4200-E_Linux_SIO_Driver-v1.4.zip and is based on this
updated to use the LED subsystem with the ioctl and hardware
monitor support removed.
I don't have any need for brightness
control, and its code is *completely* separate from the on/off
controls implemented here. If anyone else wants it, I'd be
happy to look into adding it, but I don't care enough for now.
Except for the probe routines, I rewrote most of it. I also
Note that I don't have any hardware documentation except for
the original driver.
Thanks go to Arjan for his help in getting the original source
for this released and for chasing down some licensing issues.

Subject: [PATCH 138/618] leds: leds-alix2c - take port address from MSR
This makes the LEDs driver for ALIX2.C boards work with Coreboot by
looking up the port address in the MSR rather than hard-coding it.
The BIOS scan also needed some tweaks as the string in Coreboot differs
from the one in the legacy BIOS.
Successfully tested with both the legacy tinyBIOS as well as Coreboot
v3.

Subject: [PATCH 140/618] leds: Add driver for LT3593 controlled LEDs
The LT3593 is a step-up DC/DC converter designed to drive up to ten
white LEDs in series. The current flow can be set with a control pin.
This driver controls any number of such devices connected on generic
GPIOs and exports the function as as platform_driver.
The gpio_led platform data struct definition is reused for this purpose.
Successfully tested on a PXA embedded board.

+Don't mess with the brightness hotkeys in a Thinkpad. If you want

-For IBM and Lenovo models *without* ACPI backlight control (the ones on
-which thinkpad-acpi will autoload its backlight interface by default,
-and on which ACPI video does not export a backlight interface):
-
-1. Don't enable or map the brightness hotkeys in thinkpad-acpi, as
- these older firmware versions unfortunately won't respect the hotkey
- mask for brightness keys anyway, and always reacts to them. This
- usually work fine, unless X.org drivers are doing something to block
- the BIOS. In that case, use (3) below. This is the default mode of
- operation.
-
-2. Enable the hotkeys, but map them to something else that is NOT
- KEY_BRIGHTNESS_UP/DOWN or any other keycode that would cause
- userspace to try to change the backlight level, and use that as an
- on-screen-display hint.
-
-3. IF AND ONLY IF X.org drivers find a way to block the firmware from
- automatically changing the brightness, enable the hotkeys and map
- them to KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN, and feed that to
- something that calls xbacklight. thinkpad-acpi will not be able to
- change brightness in that case either, so you should disable its
- backlight interface.
-
-For Lenovo models *with* ACPI backlight control:
-
-1. Load up ACPI video and use that. ACPI video will report ACPI
- events for brightness change keys. Do not mess with thinkpad-acpi
- defaults in this case. thinkpad-acpi should not have anything to do
- with backlight events in a scenario where ACPI video is loaded:
- brightness hotkeys must be disabled, and the backlight interface is
- to be kept disabled as well. This is the default mode of operation.
-
-2. Do *NOT* load up ACPI video, enable the hotkeys in thinkpad-acpi,
- and map them to KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN. Process
- these keys on userspace somehow (e.g. by calling xbacklight).
- The driver will do this automatically if it detects that ACPI video
- has been disabled.
+The driver will issue KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN events
+automatically for the cases were userspace has to do something to
+implement brightness changes. When you override these events, you will
+either fail to handle properly the ThinkPads that require explicit
+action to change backlight brightness, or the ThinkPads that require
+that no action be taken to work properly.

Subject: [PATCH 147/618] sched: Fix set_cpu_active() in cpu_down()
Sachin found cpu hotplug test failures on powerpc, which made
the kernel hang on his POWER box.
The problem is that we fail to re-activate a cpu when a
hot-unplug fails. Fix this by moving the de-activation into
_cpu_down after doing the initial checks.
Remove the synchronize_sched() calls and rely on those implied
by rebuilding the sched domains using the new mask.

Subject: [PATCH 151/618] sched: Ensure set_task_cpu() is never called on
blocked tasks
In order to clean up the set_task_cpu() rq dependencies we need
to ensure it is never called on blocked tasks because such usage
does not pair with consistent rq->lock usage.
This puts the migration burden on ttwu().
Furthermore we need to close a race against changing
->cpus_allowed, since select_task_rq() runs with only preemption
disabled.
For sched_fork() this is safe because the child isn't in the
tasklist yet, for wakeup we fix this by synchronizing
set_cpus_allowed_ptr() against TASK_WAKING, which leaves
sched_exec to be a problem
This also closes a hole in (6ad4c1888 sched: Fix balance vs
hotplug race) where ->select_task_rq() doesn't validate the
result against the sched_domain/root_domain.

Subject: [PATCH 152/618] sched: Fix sched_exec() balancing
Since we access ->cpus_allowed without holding rq->lock we need
a retry loop to validate the result, this comes for near free
when we merge sched_migrate_task() into sched_exec() since that
already does the needed check.

Subject: [PATCH 153/618] sched: Fix select_task_rq() vs hotplug issues
Since select_task_rq() is now responsible for guaranteeing
->cpus_allowed and cpu_active_mask, we need to verify this.
select_task_rq_rt() can blindly return
smp_processor_id()/task_cpu() without checking the valid masks,
select_task_rq_fair() can do the same in the rare case that all
SD_flags are disabled.

Subject: [PATCH 156/618] sched: Remove the cfs_rq dependency from
set_task_cpu()
In order to remove the cfs_rq dependency from set_task_cpu() we
need to ensure the task is cfs_rq invariant for all callsites.
The simple approach is to substract cfs_rq->min_vruntime from
se->vruntime on dequeue, and add cfs_rq->min_vruntime on
enqueue.
However, this has the downside of breaking FAIR_SLEEPERS since
we loose the old vruntime as we only maintain the relative
position.
To solve this, we observe that we only migrate runnable tasks,
we do this using deactivate_task(.sleep=0) and
activate_task(.wakeup=0), therefore we can restrain the
min_vruntime invariance to that state.
The only other case is wakeup balancing, since we want to
maintain the old vruntime we cannot make it relative on dequeue,
but since we don't migrate inactive tasks, we can do so right
before we activate it again.
This is where we need the new pre-wakeup hook, we need to call
this while still holding the old rq->lock. We could fold it into
->select_task_rq(), but since that has multiple callsites and
would obfuscate the locking requirements, that seems like a
fudge.
This leaves the fork() case, simply make sure that ->task_fork()
leaves the ->vruntime in a relative state.
This covers all cases where set_task_cpu() gets called, and
ensures it sees a relative vruntime.

+Description
+-----------
+
+This driver permits reading of the internal temperature sensor of AMD
+Family 10h and 11h processors.
+
+All these processors have a sensor, but on older revisions of Family 10h
+processors, the sensor may return inconsistent values (erratum 319). The
+driver will refuse to load on these revisions unless you specify the
+"force=1" module parameter.
+
+There is one temperature measurement value, available as temp1_input in
+sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree.
+Please note that it is defined as a relative value; to quote the AMD manual:
+
+ Tctl is the processor temperature control value, used by the platform to
+ control cooling systems. Tctl is a non-physical temperature on an
+ arbitrary scale measured in degrees. It does _not_ represent an actual
+ physical temperature like die or case temperature. Instead, it specifies
+ the processor temperature relative to the point at which the system must
+ supply the maximum cooling for the processor's specified maximum case
+ temperature and maximum thermal power dissipation.
+
+The maximum value for Tctl is available in the file temp1_max.
+
+If the BIOS has enabled hardware temperature control, the threshold at
+which the processor will throttle itself to avoid damage is available in
+temp1_crit and temp1_crit_hyst.

Subject: [PATCH 161/618] hwmon: (smsc47m1) Only request I/O ports we really
use
The I/O area of the SMSC LPC47M1xx chips which we use, gives access to
a lot of registers, some of which are related to fan speed monitoring
and control, but many are not. At the moment, the smsc47m1 driver
requests the whole I/O port range. This could easily result in
resource conflicts with either ACPI or other drivers.
Request only the I/O ports we really use, to prevent such conflicts.

Subject: [PATCH 168/618] mfd: twl: fix twl4030 rename for remaining driver,
board files
Recent drivers/mfd/twl4030* renames to twl broke compile for
various boards as the series was missing a patch to change
the board-*.c files.
This patch renames include twl4030.h to include twl.h
and also renames twl4030_i2c_ routines.

This is due the fact that uart_list list was populated in
omap_serial_early_init() and omap_uart_enable_irqs() went through this
list even when serial idle wasn't enabled for all uarts.
This patch moves the code that populates the uart_list and enables uart
clocks into omap_serial_init_port().

In NOMMU mode clamp dac_mmap_min_addr to zero to cause the tests on it to be

any sense in NOMMU mode.
mmap_min_addr and round_hint_to_min() can be discarded entirely in NOMMU mode.

TIF_NOTIFY_RESUME architecture support
As of commit ee18d64c1f632043a02e6f5ba5e045bb26a5465f ("KEYS: Add a keyctl to
install a process's session keyring on its parent [try #6]"), CONFIG_KEYS=y
fails to build on architectures that haven't implemented TIF_NOTIFY_RESUME yet:
security/keys/keyctl.c: In function 'keyctl_session_to_parent':
security/keys/keyctl.c:1312: error: 'TIF_NOTIFY_RESUME' undeclared (first use in this function)
security/keys/keyctl.c:1312: error: (Each undeclared identifier is reported only once
security/keys/keyctl.c:1312: error: for each function it appears in.)
Make KEYCTL_SESSION_TO_PARENT depend on TIF_NOTIFY_RESUME until
m68k, and xtensa have implemented it.

Date: Thu, 17 Dec 2009 00:16:25 +0100
Subject: [PATCH 175/618] x86, msr: msrs_alloc/free for CONFIG_SMP=n
Randy Dunlap reported the following build error:
"When CONFIG_SMP=n, CONFIG_X86_MSR=m:
ERROR: "msrs_free" [drivers/edac/amd64_edac_mod.ko] undefined!
ERROR: "msrs_alloc" [drivers/edac/amd64_edac_mod.ko] undefined!"
This is due to the fact that <arch/x86/lib/msr.c> is conditioned on
CONFIG_SMP and in the UP case we have only the stubs in the header.
Fork off SMP functionality into a new file (msr-smp.c) and build
msrs_{alloc,free} unconditionally.

Date: Wed, 16 Dec 2009 16:25:42 -0800
Subject: [PATCH 177/618] x86, cpuid: Add "volatile" to asm in native_cpuid()
xsave_cntxt_init() does something like:
cpuid(0xd, ..); // find out what features FP/SSE/.. etc are supported
xsetbv(); // enable the features known to OS
cpuid(0xd, ..); // find out the size of the context for features enabled
Depending on what features get enabled in xsetbv(), value of the
cpuid.eax=0xd.ecx=0.ebx changes correspondingly (representing the
size of the context that is enabled).
As we don't have volatile keyword for native_cpuid(), gcc 4.1.2
optimizes away the second cpuid and the kernel continues to use
the cpuid information obtained before xsetbv(), ultimately leading to kernel
crash on processors supporting more state than the legacy FP/SSE.
Add "volatile" for native_cpuid().

Have tested the 32bit kernel on Qemu/Malta and 64bit kernel on FuLoong
Mini PC. both of them work well. and also, tested by Alexander Clouter
on an AR7 based Linksys WAG54Gv2, and by Manuel Lauss on an Alchemy
board.
This -v2 version incorporate the feedback from Ralf, and add the
following changes:
1. add .ecoff, .bin, .erec format support
2. only enable it and the debug source code for the machines we tested
3. a dozen of fixups and cleanups
and if you want to enable it for your board, please try to select
SYS_SUPPORTS_ZBOOT for it, and if the board have an 16550 compatible
uart, you can select SYS_SUPPORTS_ZBOOT_UART16550 directly. and then
sending the relative patches to Ralf.

Subject: [PATCH 189/618] MIPS: Replace all usages of CL_SIZE by
COMMAND_LINE_SIZE
The MIPS-specific macro CL_SIZE is merely aliasing the macro
COMMAND_LINE_SIZE. Other architectures use the latter; also,
COMMAND_LINE_SIZE is documented in kernel-parameters.txt, so
let's use it, and remove the alias.

Subject: [PATCH 192/618] NET: Add driver for Octeon MDIO buses.
The Octeon SOC has two types of Ethernet ports, each type with its own
driver. However, the PHYs for all the ports are controlled by a
common MDIO bus. Because the mdio driver is not associated with a
particular driver, but is instead a system level resource, we create s
stand-alone driver for it.
As for the driver, we put the register definitions in
arch/mips/include/asm/octeon where most of the other Octeon register
definitions live. This is a platform driver with the platform device
for "mdio-octeon" being registered in the platform startup code.

From d6aa60a10b2f5068e331ca2936b1e6c248ae37c1 Mon Sep 17 00:00:00 2001
From: David Daney <ddaney@caviumnetworks.com>
Date: Wed, 14 Oct 2009 12:04:41 -0700
Subject: [PATCH 195/618] NET: Add Ethernet driver for Octeon MGMT devices.
The Octeon MGMT Ethernet ports are present in some members of the
Octeon SOC family (cn52XX and cn56XX have them).
The mdio bus connected to the MGMT PHYs is shared with the main
octeon-ethernet driver, we force it to be loaded first by calling
octeon_mdiobus_force_mod_depencency. The platform devices for the
MGMT Ethernet ports are added in
arch/mips/cavium-octeon/octeon-platform.c, and the register
definitions for the ports live in arch/mips/include/asm/octeon/ along
with their ilk.
Although it currently is the only driver in drivers/net/octeon, the
directory was created looking forward to the day that octeon-ethernet
will move there from its current home in drivers/staging.

Subject: [PATCH 196/618] Staging: octeon-ethernet: Convert to use PHY
Abstraction Layer.
The octeon-ethernet driver shares an mdio bus with the octeon-mgmt
driver. Here we convert the octeon-ethernet driver to use the PHY
Abstraction Layer.

Subject: [PATCH 198/618] MIPS: Put PGD in C0_CONTEXT for 64-bit R2 processors.
Processors that support the mips64r2 ISA can in four instructions
convert a shifted PGD pointer stored in the upper bits of c0_context
into a usable pointer. By doing this we save a memory load and
associated potential cache miss in the TLB exception handlers.
Since the upper bits of c0_context were holding the CPU number, we
move this to the upper bits of c0_xcontext which doesn't have enough
bits to hold the PGD pointer, but has plenty for the CPU number.

Subject: [PATCH 199/618] MIPS: MIPSsim: Remove unused code
The function prom_init_cmdline() doesn't do anything, and nobody calls the
prom_getcmdline() function. Since these two are the only functions in the
file arch/mips/mipssim/sim_cmdline.c, the whole file can be removed now
along with the call to the no-op prom_init_cmdline() routine.

Subject: [PATCH 202/618] MIPS: Loongson early_printk: Fix variable type of
uart_base
The uart_base variable here is not a physical address, so, we replace it
by unsigned char *.

Subject: [PATCH 203/618] MIPS: Loongson: Add serial port support
This patch add serial port support for all of the existing loongson
family machines. most of the board specific part are put in serial.c,
and the base address of the serial ports are defined as macros in
machine.h for sharing it between serial.c and early_printk.c

Subject: [PATCH 204/618] MIPS: Bonito64: Make Loongson independent from
Bonito64 code.
The built-in Loongson 2E/2F northbridge in is bonito64-compatible but not
identical with it. To avoid influencing the original bonito64 support and
make the loongson support more maintainable, it's better to separate the
Bonito64 code from the Loongson code.
This also prepares the kernel for the coming Loongson 2f machines family
support.

Date: Thu, 5 Nov 2009 11:34:26 -0800
Subject: [PATCH 207/618] MIPS: Collect FPU emulator statistics per-CPU.
On SMP systems, the collection of statistics can cause cache line
bouncing in the lines associated with the counters. Also there are
races incrementing the counters on multiple CPUs.
To fix both problems, we collect the statistics in per-CPU variables,
and add them up in the debugfs read operation.
As a test I ran the LTP float_bessel test on a 12 CPU Octeon system.
Without CONFIG_DEBUG_FS : 2602 seconds.
With CONFIG_DEBUG_FS: 2640 seconds.
With non-cpu-local atomic statistics: 14569 seconds.

Subject: [PATCH 208/618] MIPS: Loongson: Cleanup machtype support
To choose code for different machines by the value of machtype it needs to
be initialized as early as possible. So move initialization of
mips_machtype to prom_init().

Subject: [PATCH 209/618] MIPS: Loongson: Cleanup the serial port support
To share the same kernel image amon different machines we have added the
machtype command line support.
In the old serial port implementation the UART base address is hardcoded as
a macro in machine.h which breaks with machtype, so change that to discover
the address dynamically. Also move the initialization of the UART base
address to uart_base.c to avoid remapping twice for early_printk.c and
serial.c.

Subject: [PATCH 210/618] MIPS: oprofile: Only do performance counter handling
for counter interrupts
In Loongson2f IP6 is shared by bonito and perfcounters so we need to avoid
do_IRQ for perfcounter when the interrupt is from bonito.

Subject: [PATCH 211/618] MIPS: Loongson: Add basic Loongson 2F support
Loongson 2F has built-in DDR2 and PCI-X controller. The PCI-X controller
has a programming interface similiar to the the FPGA northbridge used on
Loongson 2E.
The main differences between Loongson 2E and Loongson 2F include:
1. Loongson 2F has an extra address window configuration module, which
is used to map CPU address space to DDR or PCI address space, or map
the PCI-DMA address space to DDR or LIO address space.
2. Loongson 2F supports 8 levels of software configurable CPu frequency
which can be configured in the LOONGSON_CHIPCFG0 register. The coming
cpufreq and standby support are based on this feature.
Loongson.h abstracts the modules and corresponding methods are abstracted.
Add other Loongson-2F-specific source code including gcc 4.4 support, PCI
memory space, PCI IO space, DMA address.

Subject: [PATCH 213/618] MIPS: Lemote 2f: Enable legacy RTC driver
Currently rtclib is not available on Loongson family machines but the
legacy RTC driver works well on them. Deselect RTC_LIB to allow the legacy
RTC driver to be selected.
The rtclib patch series
http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=a91e34bf2595157830d599cb66becd52247b1819.1257383766.git.wuzhangjin%40gmail.com
or, in patchworks:
http://patchwork.linux-mips.org/patch/570/
http://patchwork.linux-mips.org/patch/571/
http://patchwork.linux-mips.org/patch/572/
is eventually going to switch Lemote platforms to rtclib.

Subject: [PATCH 214/618] MIPS: Lemote 2F: Add basic CS5536 VSM support
Lemote Loongson 2F family machines use CS5536 as their south bridge and need
these lowlevel interfaces to access the devices on CS5536.
Virtualize the legacy devices on CS5536 as PCI devices. This way users can
access the CS5536 PCI config space directly as a normal multi-function
PCI 2.2 device.

Subject: [PATCH 215/618] MIPS: Lemote 2F: Add PCI support
PCI support for the Fuloong 2E and Lemote Loongson 2F family machines is
mostly identical with the exception of CS5536 support.
Rename ops-fuloong2e.c to ops-loongson2.c then add the CS5536 support to
share most of the source code among Loongson machines.

Subject: [PATCH 216/618] MIPS: Lemote 2F: Add IRQ support
The generic i8259_irq() will make kernel hang on booting, so Loongson 2F
needs its own polling method.
IP6 is shared by the bonito interrupt and perfcounter interrupts.

Subject: [PATCH 218/618] MIPS: Lemote 2F: Add defconfig file
Add default config file for Lemote Loongson 2F family machines. The
resulting kernel image can be shared between Fuloong 2F, Yeeloong 2F and
other Lemote Loongson 2F family machines.
If you are using an old PMON, and not using a 2f box, please add a new
command line argument in the boot.cfg.
For example, add this argument for 8.9inches notebook:
machtype=lemote-yeeloong-2f-8.9inches
or
machtype=8.9
More information from arch/mips/loongson/common/machtype.c.

Subject: [PATCH 219/618] MIPS: Loongson 2F: Cleanup the #if clauses
This patch adds two new kernel options: CPU_SUPPORTS_CPUFREQ and
CPU_SUPPORTS_ADDRWINCFG to describe the new features of Loongons 2F and
replaces the several ugly #if clauses by them.
These two options will be utilized by the future loongson revisions and
related drivers such as the coming Loongson 2F CPUFreq driver.

Subject: [PATCH 221/618] MIPS: Loongson 2F: Add suspend support framework
This patch add basic suspend support for loongson2f family machines,
loongson2f have a specific feature: when we set it's frequency to ZERO,
it will go into a wait mode, and then can be waked up by the external
interrupt. so, if we setup suitable interrupts before putting it into
wait mode, we will be able wake it up whenever we want via sending the
relative interrupts to it.
These interrupts are board-specific, Yeeloong2F use the keyboard
interrupt and SCI interrupt, but LingLoong and Fuloong2F use the
interrupts connected to the processors directly. and BTW: some old
LingLoong and FuLoong2F have no such interrupts connected, so, there is
no way to wake them up from suspend mode. and therefore, please do not
enable the kernel support for them.
The board-specific support will be added in the coming patches.

Subject: [PATCH 222/618] MIPS: Yeeloong 2F: Add board specific suspend support
Lemote Loongson 2F family machines need an external interrupt to wake the
system from the suspend mode.
For YeeLoong 2F and Mengloong 2F setup the keyboard interrupt as the wakeup
interrupt.
The new Fuloong 2F and LingLoong 2F have a button to directly send an
interrupt to the CPU so there is no need to setup an interrupt.

Subject: [PATCH 224/618] MIPS: PowerTV: Base files for Cisco PowerTV platform
Add the Cisco Powertv cable settop box to the MIPS tree. This platform is
based on a MIPS 24Kc processor with various devices integrated on the same
ASIC. There are multiple models of this box, with differing configuration
but the same kernel runs across the product line.

+ *
+ * The problem we are solving is that, when random_ether_addr() is used to
+ * generate MAC addresses at startup, there isn't much entropy for the random
+ * number generator to use and the addresses it produces are fairly likely to
+ * be the same as those of other identical systems on the same local network.
+ * This is true even for relatively small numbers of systems (for the reason
+ * why, see the Wikipedia entry for "Birthday problem" at:
+ * http://en.wikipedia.org/wiki/Birthday_problem
+ *
+ * The good news is that we already have a MAC address known to be unique, the
+ * RF MAC address. The bad news is that this address is already in use on the
+ * RF interface. Worse, the obvious trick, taking the RF MAC address and
+ * turning on the locally managed bit, has already been used for other devices.
+ * Still, this does give us something to work with.
+ *
+ * The approach we take is:
+ * 1. If we can't get the RF MAC Address, just call random_ether_addr.
+ * 2. Use the 24-bit NIC-specific bits of the RF MAC address as the last 24
+ * bits of the new address. This is very likely to be unique, except for
+ * the current box.
+ * 3. To avoid using addresses already on the current box, we set the top
+ * six bits of the address with a value different from any currently
+ * registered Scientific Atlanta organizationally unique identifyer
+ * (OUI). This avoids duplication with any addresses on the system that
+ * were generated from valid Scientific Atlanta-registered address by
+ * simply flipping the locally managed bit.
+ * 4. We aren't generating a multicast address, so we leave the multicast
+ * bit off. Since we aren't using a registered address, we have to set
+ * the locally managed bit.
+ * 5. We then randomly generate the remaining 16-bits. This does two
+ * things:
+ * a. It allows us to call this function for more than one device
+ * in this system
+ * b. It ensures that things will probably still work even if
+ * some device on the device network has a locally managed
+ * address that matches the top six bits from step 2.

Subject: [PATCH 225/618] MIPS: Lemote 2F: Add NAS support
Kernel support for this machine is almost the same as Fuloong 2F; the only
difference is that it uses the serial port provided by Loongson 2F processor
as Yeeloong 2F does.

Subject: [PATCH 227/618] MIPS: Lemote 2F: Add cs5536 MFGPT timer support
CPUFreq support for Loongson 2F requires an external timer.
Because the frequency of the MIPS Timer is related to the CPU frequency
which itself is variable another timer of constant frequency is required.
Export the mfgpt0 counter disable / enable operations for the coming
suspend support to suspend / resume the timer.

Subject: [PATCH 228/618] MIPS: Add basic CPUFreq options.
This patch adds basic options for MIPS CPUFreq support.
Since the cp0 timer's frequency is based on the processor clockrate it can
not be used with CPUFReq; an additional external timer is required.

Subject: [PATCH 229/618] MIPS: Loongson 2F: Add CPU frequency scaling support
Loongson 2F supports CPU clock scaling. When put it into wait mode by
setting the frequency as ZERO it will stay in this mode until an external
interrupt wakes the CPU again.
To enable clock scaling support, an external timer of a known stable rate
is required.

Subject: [PATCH 231/618] MIPS: Tracing: Add static function tracer support for
MIPS
If -pg of gcc is enabled with CONFIG_FUNCTION_TRACER=y. a calling to
_mcount will be inserted into each kernel function. so, there is a
possibility to trace the kernel functions in _mcount.
This patch add the MIPS specific _mcount support for static function
tracing. by default, ftrace_trace_function is initialized as
ftrace_stub(an empty function), so, the default _mcount will introduce
very little overhead. after enabling ftrace in user-space, it will jump
to a real tracing function and do static function tracing for us.
and -ffunction-sections is incompatible with -pg, so, disable it when
ftracer is enabled.

Subject: [PATCH 234/618] MIPS: Tracing: Add dynamic function tracer support
With dynamic function tracer, by default, _mcount is defined as an
"empty" function, it returns directly without any more action . When
enabling it in user-space, it will jump to a real tracing
function(ftrace_caller), and do the real job for us.
Differ from the static function tracer, dynamic function tracer provides
two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the
tracing of some indicated kernel functions(set_ftrace_filter).
In the -v4 version, the implementation of this support is basically the same as
X86 version does: _mcount is implemented as an empty function and ftrace_caller
is implemented as a real tracing function respectively.
But in this version, to support module tracing with the help of
-mlong-calls in arch/mips/Makefile:
MODFLAGS += -mlong-calls.
The stuff becomes a little more complex. We need to cope with two
different type of calling to _mcount.
For the kernel part, the calling to _mcount(result of "objdump -hdr
vmlinux"). is like this:
108: 03e0082d move at,ra
10c: 0c000000 jal 0 <fpcsr_pending>
10c: R_MIPS_26 _mcount
10c: R_MIPS_NONE *ABS*
10c: R_MIPS_NONE *ABS*
110: 00020021 nop
For the module with -mlong-calls, it looks like this:
c: 3c030000 lui v1,0x0
c: R_MIPS_HI16 _mcount
c: R_MIPS_NONE *ABS*
c: R_MIPS_NONE *ABS*
10: 64630000 daddiu v1,v1,0
10: R_MIPS_LO16 _mcount
10: R_MIPS_NONE *ABS*
10: R_MIPS_NONE *ABS*
14: 03e0082d move at,ra
18: 0060f809 jalr v1
In the kernel version, there is only one "_mcount" string for every
kernel function, so, we just need to match this one in mcount_regex of
scripts/recordmcount.pl, but in the module version, we need to choose
one of the two to match. Herein, I choose the first one with
"R_MIPS_HI16 _mcount".
and In the kernel verion, without module tracing support, we just need
to replace "jal _mcount" by "jal ftrace_caller" to do real tracing, and
filter the tracing of some kernel functions via replacing it by a nop
instruction.
but as we have described before, the instruction "jal ftrace_caller" only left
32bit length for the address of ftrace_caller, it will fail when calling from
the module space. so, herein, we must replace something else.
the basic idea is loading the address of ftrace_caller to v1 via changing these
two instructions:
lui v1,0x0
addiu v1,v1,0
If we want to enable the tracing, we need to replace the above instructions to:
lui v1, HI_16BIT_ftrace_caller
addiu v1, v1, LOW_16BIT_ftrace_caller
If we want to stop the tracing of the indicated kernel functions, we
just need to replace the "jalr v1" to a nop instruction. but we need to
replace two instructions and encode the above two instructions
oursevles.
Is there a simpler solution? Yes! Here it is, in this version, we put _mcount
and ftrace_caller together, which means the address of _mcount and
ftrace_caller is the same:
_mcount:
ftrace_caller:
j ftrace_stub
nop
...(do real tracing here)...
ftrace_stub:
jr ra
move ra, at
By default, the kernel functions call _mcount, and then jump to ftrace_stub and
return. and when we want to do real tracing, we just need to remove that "j
ftrace_stub", and it will run through the two "nop" instructions and then do
the real tracing job.
what about filtering job? we just need to do this:
lui v1, hi_16bit_of_mcount <--> b 1f (0x10000004)
addiu v1, v1, low_16bit_of_mcount
move at, ra
jalr v1
nop
1f: (rec->ip + 12)
In linux-mips64, there will be some local symbols, whose name are
prefixed by $L, which need to be filtered. thanks goes to Steven for
writing the mips64-specific function_regex.
In a conclusion, with RISC, things becomes easier with such a "stupid"
trick, RISC is something like K.I.S.S, and also, there are lots of
"simple" tricks in the whole ftrace support, thanks goes to Steven and
the other folks for providing such a wonderful tracing framework!

Subject: [PATCH 235/618] MIPS: Tracing: Add IRQENTRY_EXIT section for MIPS
This patch add a new section for MIPS to record the block of the hardirq
handling for function graph tracer(print_graph_irq) via adding the
__irq_entry annotation to the the entrypoints of the hardirqs(the block
with irq_enter()...irq_exit()).
Thanks goes to Steven & Frederic Weisbecker for their feedbacks.

Subject: [PATCH 236/618] MIPS: Tracing: Add function graph tracer support for
MIPS
The implementation of function graph tracer for MIPS is a little
different from X86.
in MIPS, gcc(with -pg) only transfer the caller's return address(at) and
the _mcount's return address(ra) to us.
For the kernel part without -mlong-calls:
move at, ra
jal _mcount
For the module part with -mlong-calls:
lui v1, hi16bit_of_mcount
addiu v1, v1, low16bit_of_mcount
move at, ra
jal _mcount
Without -mlong-calls,
if the function is a leaf, it will not save the return address(ra):
ffffffff80101298 <au1k_wait>:
ffffffff80101298: 67bdfff0 daddiu sp,sp,-16
ffffffff8010129c: ffbe0008 sd s8,8(sp)
ffffffff801012a0: 03a0f02d move s8,sp
ffffffff801012a4: 03e0082d move at,ra
ffffffff801012a8: 0c042930 jal ffffffff8010a4c0 <_mcount>
ffffffff801012ac: 00020021 nop
so, we can hijack it directly in _mcount, but if the function is non-leaf, the
return address is saved in the stack.
ffffffff80133030 <copy_process>:
ffffffff80133030: 67bdff50 daddiu sp,sp,-176
ffffffff80133034: ffbe00a0 sd s8,160(sp)
ffffffff80133038: 03a0f02d move s8,sp
ffffffff8013303c: ffbf00a8 sd ra,168(sp)
ffffffff80133040: ffb70098 sd s7,152(sp)
ffffffff80133044: ffb60090 sd s6,144(sp)
ffffffff80133048: ffb50088 sd s5,136(sp)
ffffffff8013304c: ffb40080 sd s4,128(sp)
ffffffff80133050: ffb30078 sd s3,120(sp)
ffffffff80133054: ffb20070 sd s2,112(sp)
ffffffff80133058: ffb10068 sd s1,104(sp)
ffffffff8013305c: ffb00060 sd s0,96(sp)
ffffffff80133060: 03e0082d move at,ra
ffffffff80133064: 0c042930 jal ffffffff8010a4c0 <_mcount>
ffffffff80133068: 00020021 nop
but we can not get the exact stack address(which saved ra) directly in
_mcount, we need to search the content of at register in the stack space
or search the "s{d,w} ra, offset(sp)" instruction in the text. 'Cause we
can not prove there is only a match in the stack space, so, we search
the text instead.
as we can see, if the first instruction above "move at, ra" is not a
store instruction, there should be a leaf function, so we hijack the at
register directly via putting &return_to_handler into it, otherwise, we
search the "s{d,w} ra, offset(sp)" instruction to get the stack offset,
and then the stack address. we use the above copy_process() as an
example, we at last find "ffbf00a8", 0xa8 is the stack offset, we plus
it with s8(fp), that is the stack address, we hijack the content via
writing the &return_to_handler in.
If with -mlong-calls, since there are two more instructions above "move
at, ra", so, we can move the pointer to the position above "lui v1,
hi16bit_of_mcount".

Subject: [PATCH 237/618] MIPS: Tracing: Add dynamic function graph tracer for
MIPS
This patch make function graph tracer work with dynamic function tracer.
To share the source code of dynamic function tracer(MCOUNT_SAVE_REGS),
and avoid restoring the whole saved registers, we need to restore the ra
register from the stack.
(NOTE: This not work with 32bit! need to ensure why!)

Subject: [PATCH 239/618] MIPS: Tracing: Reserve $12(t0) for mcount-ra-address
of gcc 4.5
A new option -mmcount-ra-address for gcc 4.5 have been sent by David
Daney <ddaney@caviumnetworks.com> in the thread "MIPS: Add option to
pass return address location to _mcount", which help to record the
location of the return address(ra) for the function graph tracer of MIPS
to hijack the return address easier and safer. that option used the
$12(t0) register by default, so, we reserve it for it, and use t1,t2,t3
instead of t0,t1,t2.

easier and safer to hijack the return address of the kernel function,
which will save some overhead and make the whole thing more reliable.
In this patch, at first, try to enable the option -mmcount-ra-address in
arch/mips/Makefile with cc-option, if gcc support it, it will be
enabled, otherwise, no side effect.
and then, we need to support this new option of gcc 4.5 and also support
the old gcc versions.
with _mcount in the old gcc versions, it's not easy to get the location
of return address(tracing: add function graph tracer support for MIPS),
so, we do it in a C function: ftrace_get_parent_addr(ftrace.c), but
with -mmcount-ra-address, only several instructions need to get what
we want, so, I put into asm(mcount.S). and also, as the $12(t0) is
used by -mmcount-ra-address for transferring the localtion of return
address to _mcount, we need to save it into the stack and restore it
when enabled dynamic function tracer, 'Cause we have called
"ftrace_call" before "ftrace_graph_caller", which may destroy
$12(t0).
(Thanks to David for providing that -mcount-ra-address and giving the
idea of KBUILD_MCOUNT_RA_ADDRESS, both of them have made the whole
thing more beautiful!)

Subject: [PATCH 241/618] MIPS: Move several variables from .bss to .init.data
Several static uninitialized variables are used in the scope of __init
functions but are themselves not marked as __initdata. This patch is to put
those variables to where they belong and to reduce the memory footprint a
little bit.
Also, a couple of lines with spaces instead of tabs were fixed.

Subject: [PATCH 243/618] MIPS: Yeeloong 2F: Add LID open event as the wakeup
event
Yeeloong 2F netbook has an KB3310B embedded controller to manage the LID
action. When the LID is closed or opened a SCI interrupt is sent out and
the corresponding event is saved to an EC register for later query.
Allow the LID open interrupt to wake the processor from wait mode if it is
in the suspend mode.

Subject: [PATCH 251/618] MIPS: Loongson: Cleanups of serial port support
This patchs uses a loongson_uart_base variable instead of the
uart_base[] array and adds a new kernel option to avoid to compile
uart_base.c all the time, which will save a little bit of memory for us.

From 6acc7d485c24c00e111c61b2e6dff9180faebcae Mon Sep 17 00:00:00 2001
From: Dmitri Vorobiev <dmitri.vorobiev@movial.com>
Date: Sat, 21 Nov 2009 22:34:41 +0200
Subject: [PATCH 253/618] MIPS: Fix and enhance built-in kernel command line
Currently, MIPS kernels silently overwrite kernel command-line parameters
hardcoded in CONFIG_CMDLINE by the ones received from firmware. Therefore,
using firmware remains the only reliable method to transfer the
command-line parameters, which is not always desirable or convenient, and
the CONFIG_CMDLINE option is thereby effectively rendered useless.
This patch fixes the problem described above and introduces a more flexible
scheme of handling the kernel command line, in a manner identical to what is
currently used for x86. The default behavior, i.e. when CONFIG_CMDLINE_BOOL
is not defined, retains the existing semantics, and firmware command-line
arguments override the hardcoded ones.
[Ralf: I fixed up all the defconfig files so the stay unaffected by this
change.]

Subject: [PATCH 254/618] MIPS: No longer hardwire CONFIG_EMBEDDED to y
There's no reason for MIPS to select EMBEDDED. In fact, EMBEDDED makes
MIPS more awkward to deal with because it makes it different to the
majority of architectures for no good reason.
[Ralf: Historically disabling EMBEDDED had hid essential options for many
MIPS platforms such as serial console and forced crap like VGA support
or power managment enabled for platforms where those don't make any sense.
The name of the option is also _very_ missleading so many users don't
select it even where is was required for a functioning kernel.]

Subject: [PATCH 267/618] libata: fix reporting of drained bytes when clearing
DRQ
When we drain data from a device to clear DRQ during error recovery,
the number of bytes reported as drained is too low by a factor of 2
because the count is actually reporting the number of words drained,
not bytes. Fix this.

Subject: [PATCH 268/618] pata_hpt3x2n: fix clock turnaround
The clock turnaround code still doesn't work for several reasons:
- 'USE_DPLL' flag in 'ap->host->private_data' is never initialized
or updated, so the driver can only set the chip to the DPLL clock
mode, not the PCI mode;
- the driver doesn't serialize access to the channels depending on
the current clock mode like the vendor drivers, so the clock
turnaround is only executed "optionally", not always as it should be;
- the wrong ports are written to when hpt3x2n_set_clock() is called
for the secondary channel;
- hpt3x2n_set_clock() can inadvertently enable the disabled channels
when resetting the channel state machines.

Subject: [PATCH 270/618] perf probe: Fix libdwarf include path for Debian
Fix libdwarf include path to fit debian-like systems too.
Borislav Petkov reported:
> even after installing libdwarf-dev on my debian box here,
> make in tools/perf/ still complains that it cannot find libdwarf:
>
> Makefile:491: No libdwarf.h found or old libdwarf.h found, disables dwarf

>
> The problem is that the include path on debian is not
> /usr/include/libdwarf/ but simply /usr/include because the debian
> package libdwarf-dev puts the headers straight into
> /usr/include.
This patch adds -I/usr/include/libdwarf to BASIC_CFLAGS
and fix probe-finder.h to include just libdwarf.h/dwarf.h.
This patch also adds a workaround for the undefined _MIPS_SZLONG
bug in libdwarf.h.

Subject: [PATCH 272/618] kprobe-tracer: Check new event/group name
Check new event/group name is same syntax as a C symbol. In other
words, checking the name is as like as other tracepoint events.
This can prevent user to create an event with useless name (e.g.
foo|bar, foo*bar).

Subject: [PATCH 274/618] sched: Teach might_sleep() about preemptible RCU
In practice, it is harmless to voluntarily sleep in a
rcu_read_lock() section if we are running under preempt rcu, but
it is illegal if we build a kernel running non-preemptable rcu.
Currently, might_sleep() doesn't notice sleepable operations
under rcu_read_lock() sections if we are running under
preemptable rcu because preempt_count() is left untouched after
rcu_read_lock() in this case. But we want developers who test
their changes under such config to notice the "sleeping while
atomic" issues.
So we add rcu_read_lock_nesting to prempt_count() in
might_sleep() checks.

Subject: [PATCH 276/618] perf events, x86/stacktrace: Make stack walking
optional
The current print_context_stack helper that does the stack
walking job is good for usual stacktraces as it walks through
all the stack and reports even addresses that look unreliable,
which is nice when we don't have frame pointers for example.
But we have users like perf that only require reliable
stacktraces, and those may want a more adapted stack walker, so
lets make this function a callback in stacktrace_ops that users
can tune for their needs.

Subject: [PATCH 277/618] perf events, x86/stacktrace: Fix
performance/softlockup by providing a special frame pointer-only stack walker
It's just wasteful for stacktrace users like perf to walk
through every entries on the stack whereas these only accept
reliable ones, ie: that the frame pointer validates.
Since perf requires pure reliable stacktraces, it needs a stack
walker based on frame pointers-only to optimize the stacktrace
processing.
This might solve some near-lockup scenarios that can be triggered
by call-graph tracing timer events.

From e24a04c44cf312e88b50006a91ad7ffc1c0d97a5 Mon Sep 17 00:00:00 2001
From: Mark Brown <broonie@opensource.wolfsonmicro.com>
Date: Tue, 22 Sep 2009 08:47:11 -0700
Subject: [PATCH 280/618] regulator: Implement WM831x BuckWise DC-DC convertor
DVS support
The BuckWise DC-DC convertors in WM831x devices support switching to
a second output voltage using the logic level on one of the device
pins. This is intended to allow rapid voltage switching for uses like
cpufreq, replacing the I2C or SPI write used to configure the voltage
of the regulator with a much faster GPIO status change.
This is implemented by keeping the DVS voltage configured as the
maximum voltage permitted for the regulator. If a request is made
for the maximum voltage then the GPIO is used to switch to the DVS
voltage, otherwise the normal ON voltage is updated and used. This
follows the idiom used by most cpufreq drivers, which drop the
minimum voltage as the core frequency is dropped but use a constant
maximum - raising the voltage should normally be fast, but lowering
it may be slower.
Configuration of the DVS MFP on the device should be done externally,
for example via OTP.
Support is present in the hardware for monitoring the status of the
transition using a second GPIO. This is not currently implemented
but platform data is provided for it - the driver currently assumes
that the device will be configured to transition immediately - but
platform data is provided to reduce merge issues once it is.

This allows constraints to take effect on regulators that support
voltage setting but for which the board does not specify a voltage
range (for example, because it is fixed correctly at system startup).

Subject: [PATCH 286/618] regulator: Factor out regulator name pretty printing
Some of the regulator API functions have code to allow the machine
constraints to override the device supplied name for the regulator
in the constraints in order to help tie logging to supplies on the
board and disambiguate when there is more than one regulator chip
in the system. Factor this code out into a new rdev_get_name()
function and use it throughout the regulator API so that we always
use the same name.

Subject: [PATCH 287/618] regulator: Handle regulators without suspend mode
configuration
Since some regulators in the system may not support suspend mode
configuration we need to allow some regulators to have a missing
suspend mode configuration. Do this by requiring that disabled
regulators are explicitly flagged and then skip over regulators
that have no state specified.
Try to avoid surprises by warning the if we could set the state
but no configuration is provided. This also ensures that an all
zeros configuration generates a warning rather than silently
disabling the regulator.

Subject: [PATCH 289/618] regulator: Ensure val is initialised in 88pm8607
choose_voltage()
If we fall through it means that we hit an unknown regulator/chip
combination so set -ENOENT as an explicit flag (the return code
is only used internally).

Subject: [PATCH 291/618] Fix some AB3100 regulator issues
This patch will remove surplus register writes on shut down of
LDO D (this magic was not needed), remove an unnecessary (!) error
check and really unregister the regulators when the module is
unloaded.

One annoying thing about the old name was that the module was just
called mc13783 which caused wrong expectations (at least for me).

Subject: [PATCH 293/618] regulator/mc13783: various cleanups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- define needed registers and bits in the driver
- properly namespace functions and structs
- fix locking as required by patch
"mfd/mc13783: near complete rewrite"
- use platform_data as provided by "mfd/mc13783: near complete rewrite"
instead of accessing struct mc13783
- struct mc13783_regulator_priv.desc is (and was) unused and so can go
away
- use cpp magic to initialize mc13783_regulators
- bring MODULE_LICENSE in sync with actual copyright
- minor style fixes
This allows not including mc13783-private.h which I intend to remove
soon.

Currently it is possible for regulator_bulk_{enable,disable} operations to

In case of an error only those regulators of the bulk operation which actually
had been enabled/disabled should get their original state restored.

Subject: [PATCH 298/618] regulator: mc13783-regulator: correct the probing
time.
When the mc13783-regulator driver is built in kernel, probing it during
the regulator subsystem initialisation result in a fault.
That is because regulator subsystem is planned to be initialised very early
in the boot process, before the mfd subsystem initialisation.
The mc12783-regulator probing process need to access to the mc13783-core
functionality to read/write mc13783 registers and so must be called after
the mc13783-core driver initialisation.
The way to do this is to let the kernel probe the mc13783-regulator driver when
mc13783-core register his regulator subdevice.

Subject: [PATCH 301/618] twl-regulator: Add turnon-delay and REMAP config to
twlreg_info struct
This change includes regulator turnon delay values and the REMAP reset
configuration to the twlreg_info struct, since they are basic attributes
of every TWL regulator

Subject: [PATCH 314/618] leds: Add LED class driver for regulator driven LEDs.
This driver provides an interface for controlling LEDs (or vibrators)
connected to PMICs for which there is a regulator framework driver.
This driver can be used, for instance, to control vibrator on all Motorola EZX
phones using the pcap-regulator driver services.

Fixed initialization of internal mic and added internal mic boost control
Renamed analog mic boost control to ext mic boost contol.
Name pair analog/digital seems too confusing for a normal user.

Subject: [PATCH 321/618] leds: leds-pwm: Set led_classdev max_brightness
Currently the driver leds-pwm doesn't set max_brightness for the led device
although it's platform data proides a maximum brightness. Instead it stores its
own private driver struct. The max_brightness defaults to 255 for led device if
it has not been set.
As a result any leds-pwm device with a different maximum brightness will show
incorrect behavior, as it is posible to either set a longer then period duty
time or not be able to switch the led to full brightness.

Subject: [PATCH 324/618] perf events: Dont report side-band events on each cpu
for per-task-per-cpu events
Acme noticed that his FORK/MMAP numbers were inflated by about
the same factor as his cpu-count.
This led to the discovery of a few more sites that need to
respect the event->cpu filter.

Subject: [PATCH 329/618] sched: Fix broken assertion
There's a preemption race in the set_task_cpu() debug check in
that when we get preempted after setting task->state we'd still
be on the rq proper, but fail the test.
Check for preempted tasks, since those are always on the RQ.

Subject: [PATCH 331/618] Makefile: set LC_CTYPE, LC_COLLATE, LC_NUMERIC to C
There are a number of common Unix constructs like character ranges in
grep/sed/awk which don't work as expected with LC_COLLATE set to other
than C. Similarly, set LC_CTYPE and LC_NUMERIC to C to avoid other
nasty surprises.
In order to make sure these actually take effect we also have to
clear LC_ALL.

ASCII, we can just use explicit ranges for lower case, alphabetic, and

Subject: [PATCH 333/618] x86/ptrace: make genregs[32]_get/set more robust
The loop condition is fragile: we compare an unsigned value to zero, and
then decrement it by something larger than one in the loop. All the
callers should be passing in appropriately aligned buffer lengths, but
it's better to just not rely on it, and have some appropriate defensive
loop limits.

Subject: [PATCH 334/618] Revert "fbdev: atafb - add palette register check"
This reverts commit 8546e3ce6e37c359979b69862442f94e0ef0e03b, as it's a
partial duplicate of commit 2f390380ca69e1617cdddb12d8da94f0a9f4319d
("fbdev: add palette register check to several drivers").
The former went in first through the m68k tree, the latter through Andrew
Morton.

Subject: [PATCH 336/618] spidev: add proper section markers
The driver already uses __devexit_p() in the structure, but looks like
actual __dev{init,exit} markings were forgotten.
The spidev_spi driver also needs renaming to include a "_driver" suffix to
avoid section mismatch warnings.

Subject: [PATCH 338/618] fs: anon_inodes implement dname
Add a d_dname method for anon_inodes filesystem, the same way pipefs and
sockfs pseudo filesystems. This allows us to remove the DCACHE_UNHASHED
hack from anon_inodes.c (see next patch).
[AV: inumber is useless here, dropped from anon_inodefs_dname()]

Subject: [PATCH 339/618] fs: no games with DCACHE_UNHASHED
Filesystems outside the regular namespace do not have to clear DCACHE_UNHASHED
in order to have a working /proc/$pid/fd/XXX. Nothing in proc prevents the
fd link from being used if its dentry is not in the hash.
Also, it does not get put into the dcache hash if DCACHE_UNHASHED is clear;
that depends on the filesystem calling d_add or d_rehash.
So delete the misleading comments and needless code.

Subject: [PATCH 341/618] spi_s3c24xx: add FIQ pseudo-DMA support
Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver
to get DMA-like performance where there are either no free DMA channels or
when doing transfers that required both TX and RX data paths.
Since this patch requires the addition of an assembly file to hold the FIQ
code, we rename the module (instead of adding a rename of the .c file to
this patch). We expect most users are loading this via udev and thus
there should be no change to the userland configuration.

Subject: [PATCH 342/618] atmel_spi: fix dma addr calculation for len >
BUFFER_SIZE
If len > BUFFER_LEN and !xfer->rx_buf we end up calculating the tx buffer
address as
*tx_dma = xfer->tx_dma + xfer->len - BUFFER_SIZE;
which is constant; i.e. we just send the last BUFFER_SIZE data over again
until we've reached the right number of bytes.
This patch gets around this by using the /requested/ length when
calculating addresses.
Note there's no way len != *plen when we calculate the rx buffer address
but conceptually we should be using *plen and I don't want someone to come
through later, see the calculations for rx and tx are different and "clean
up" back to what we had.

Subject: [PATCH 344/618] spi: Add s3c64xx SPI Controller driver
Each SPI controller has exactly one CS line and as such doesn't
provide for multi-cs. We implement a workaround to support
multi-cs by _not_ configuring the mux'ed CS pin for each SPI
controller. The CS mechanism is assumed to be fully machine
specific - the driver doesn't even assume some GPIO pin is used
to control the CS.
The driver selects between DMA and POLLING mode depending upon
the xfer size - DMA mode for xfers bigger than FIFO size, POLLING
mode otherwise.
The driver has been designed to be capable of running SoCs since
s3c64xx and till date, for that reason some of the register fields
have been passed via, SoC specific, platform data.

Subject: [PATCH 345/618] VFS/fsstack: handle 32-bit smp + preempt + large
files in fsstack_copy_inode_size
Copy the inode size and blocks from one inode to another correctly on 32-bit
systems with CONFIG_SMP, CONFIG_PREEMPT, or CONFIG_LBDAF. Use proper inode
spinlocks only when i_size/i_blocks cannot fit in one 32-bit word.

Subject: [PATCH 352/618] fold do_sync_file_range into sys_sync_file_range
We recently go rid of all callers of do_sync_file_range as they're better
served with vfs_fsync or the filemap_write_and_wait. Now that
do_sync_file_range is down to a single caller fold it into it so that people
don't start using it again accidentally. While at it also switch it from
using __filemap_fdatawrite_range(..., WB_SYNC_ALL) to the more clear
filemap_fdatawrite_range().

Subject: [PATCH 354/618] Btrfs: Fix disk_i_size update corner case
There are some cases file extents are inserted without involving
ordered struct. In these cases, we update disk_i_size directly,
without checking pending ordered extent and DELALLOC bit. This
patch extends btrfs_ordered_update_i_size() to handle these cases.

Subject: [PATCH 355/618] Btrfs: Avoid orphan inodes cleanup while replaying
log
We do log replay in a single transaction, so it's not good to do unbound
operations. This patch cleans up orphan inodes cleanup after replaying
the log. It also avoids doing other unbound operations such as truncating
a file during replaying log. These unbound operations are postponed to
the orphan inode cleanup stage.

Subject: [PATCH 358/618] Btrfs: Make truncate(2) more ENOSPC friendly
truncating and deleting regular files are unbound operations,
so it's not good to do them in a single transaction. This
patch makes btrfs_truncate and btrfs_delete_inode start a
new transaction after all items in a tree leaf are deleted.

From 24bbcf0442ee04660a5a030efdbb6d03f1c275cb Mon Sep 17 00:00:00 2001
From: "Yan, Zheng" <zheng.yan@oracle.com>
Date: Thu, 12 Nov 2009 09:36:34 +0000
Subject: [PATCH 360/618] Btrfs: Add delayed iput
iput() can trigger new transactions if we are dropping the
final reference, so calling it in btrfs_commit_transaction
may end up deadlock. This patch adds delayed iput to avoid
the issue.

Subject: [PATCH 362/618] Btrfs: Fix per root used space accounting
The bytes_used field in root item was originally planned to
trace the amount of used data and tree blocks. But it never
worked right since we can't trace freeing of data accurately.
This patch changes it to only trace the amount of tree blocks.

I excluded it because we can move across subvolumes now and
it make no problem.
-----------------
Hard link across subvolumes should not allowed in Btrfs.
btrfs_link checks root of 'to' directory is same as root
of 'from' file. If not same, btrfs_link returns -EPERM.

This patch makes us a bit less zealous about making sure we have enough free
metadata space by pearing down the size of new metadata chunks to 256mb instead
of 1gb. Also, we used to try an allocate metadata chunks when allocating data,
but that sort of thing is done elsewhere now so we can just remove it. With my
-ENOSPC test I used to have 3gb reserved for metadata out of 75gb, now I have
1.7gb. Thanks,

(create_mnt_ns() export is gone now)"
This reverts commit e9496ff46a20a8592fdc7bdaaf41b45eb808d310. Quoth Al:
"it's dependent on a lot of other stuff not currently in mainline
and badly broken with current fs/namespace.c. Sorry, badly
out-of-order cherry-pick from old queue.
PS: there's a large pending series reworking the refcounting and
lifetime rules for vfsmounts that will, among other things, allow to
rip a subtree away _without_ dissolving connections in it, to be
garbage-collected when all active references are gone. It's
considerably saner wrt "is the subtree busy" logics, but it's nowhere
near being ready for merge at the moment; this changeset is one of the
things becoming possible with that sucker, but it certainly shouldn't
have been picked during this cycle. My apologies..."

Subject: [PATCH 376/618] x86: Reenable TSC sync check at boot, even with
NONSTOP_TSC
Commit 83ce4009 did the following change
If the TSC is constant and non-stop, also set it reliable.
But, there seems to be few systems that will end up with TSC warp across
sockets, depending on how the cpus come out of reset. Skipping TSC sync
test on such systems may result in time inconsistency later.
So, reenable TSC sync test even on constant and non-stop TSC systems.
Set, sched_clock_stable to 1 by default and reset it in
mark_tsc_unstable, if TSC sync fails.
This change still gives perf benefit mentioned in 83ce4009 for systems
where TSC is reliable.

Subject: [PATCH 380/618] reiserfs: truncate blocks not used by a write
It can happen that write does not use all the blocks allocated in
write_begin either because of some filesystem error (like ENOSPC) or
because page with data to write has been removed from memory. We truncate
these blocks so that we don't have dangling blocks beyond i_size.

Subject: [PATCH 386/618] do_wait() optimization: do not place sub-threads on
task_struct->children list
Thanks to Roland who pointed out de_thread() issues.
Currently we add sub-threads to ->real_parent->children list. This buys
nothing but slows down do_wait().
With this patch ->children contains only main threads (group leaders).
The only complication is that forget_original_parent() should iterate over
sub-threads by hand, and de_thread() needs another list_replace() when it
changes ->group_leader.
Henceforth do_wait_thread() can never see task_detached() && !EXIT_DEAD
tasks, we can remove this check (and we can unify do_wait_thread() and
ptrace_do_wait()).
This change can confuse the optimistic search in mm_update_next_owner(),
but this is fixable and minor.
Perhaps badness() and oom_kill_process() should be updated, but they
should be fixed in any case.

Subject: [PATCH 389/618] sdio: initialise SDIO functions and update
card->sdio_funcs in lockstep
Daniel Drake noticed a crash in the error path of mmc_attach_sdio(). This
bug is discussed at http://dev.laptop.org/ticket/9707.
BUG: unable to handle kernel paging request at 6b6b6c57
IP: [<b066d6e2>] sdio_remove_func+0x9/0x27
Call Trace:
[<b066cfb4>] ? mmc_sdio_remove+0x34/0x65
[<b066d1fc>] ? mmc_attach_sdio+0x217/0x240
[<b066a22f>] ? mmc_rescan+0x1a2/0x20f
[<b042e9a0>] ? worker_thread+0x156/0x1e
We need to accurately track how many SDIO functions have been initialised
(and keep card->sdio_funcs in sync) so that we don't try to remove more
functions than we initialised if we hit the error path in
mmc_attach_sdio().
Without this patch if we hit the error path in mmc_attach_sdio() we run
the risk of deferencing invalid memory in sdio_remove_func(), leading to a
crash.

This patch renames sdhci-of.c to sdhci-of-core.c before reorganizing the
driver to support additional hardware.
The driver is still built as sdhci-of despite the rename of the file. No

Subject: [PATCH 394/618] rtc: set wakeup capability for I2C and SPI RTC
drivers
RTC core won't allow wakeup alarms to be set if RTC devices' parent (i.e.
i2c_client or spi_device) isn't wakeup capable.
For I2C devices there is I2C_CLIENT_WAKE flag exists that we can pass via
board info, and if set, I2C core will initialize wakeup capability. For
SPI devices there is no such flag at all.
I believe that it's not platform code responsibility to allow or disallow
wakeups, instead, drivers themselves should set the capability if a device
can trigger wakeups.
That's what drivers/base/power/sysfs.c says:
* It is the responsibility of device drivers to enable (or disable)
* wakeup signaling as part of changing device power states, respecting
* the policy choices provided through the driver model.
I2C and SPI RTC devices send wakeup events via interrupt lines, so we
should set the wakeup capability if IRQ is routed.
Ideally we should also check irq for wakeup capability before setting
device's capability, i.e.
if (can_irq_wake(irq))
device_set_wakeup_capable(&client->dev, 1);
But there is no can_irq_wake() call exist, and it is not that trivial to
implement it for all interrupts controllers and complex/cascaded setups.
drivers/base/power/sysfs.c also covers these cases:
* Devices may not be able to generate wakeup events from all power
* states. Also, the events may be ignored in some configurations;
* for example, they might need help from other devices that aren't
* active
So there is no guarantee that wakeup will actually work, and so I think
there is no point in being pedantic wrt checking IRQ wakeup capability.

Subject: [PATCH 395/618] readahead: add blk_run_backing_dev
I added blk_run_backing_dev on page_cache_async_readahead so readahead I/O
is unpluged to improve throughput on especially RAID environment.
The normal case is, if page N become uptodate at time T(N), then T(N) <=
T(N+1) holds. With RAID (and NFS to some degree), there is no strict
ordering, the data arrival time depends on runtime status of individual
disks, which breaks that formula. So in do_generic_file_read(), just
after submitting the async readahead IO request, the current page may well
be uptodate, so the page won't be locked, and the block device won't be
implicitly unplugged:
if (PageReadahead(page))
page_cache_async_readahead()
if (!PageUptodate(page))
goto page_not_up_to_date;
//...
page_not_up_to_date:
lock_page_killable(page);
Therefore explicit unplugging can help.
Following is the test result with dd.

Subject: [PATCH 398/618] PM: Make the initcall_debug style timing for
suspend/resume complete
Commit f2511774863487e61b56a97da07ebf8dd61d7836
(PM: Add initcall_debug style timing for suspend/resume) introduced
basic timing instrumentation, needed for a scritps/bootgraph.pl
equivalent or humans, but it missed the fact that bus types and
device classes which haven't been switched to using struct dev_pm_ops
objects yet need special handling. As a result, the suspend/resume
timing information is only available for devices whose bus types or
device classes use struct dev_pm_ops objects, so the majority of
devices is not covered.
Fix this by adding basic suspend/resume timing instrumentation for
devices whose bus types and device classes still don't use struct
dev_pm_ops objects for power management. To reduce code duplication
move the timing code to helper functions.

Subject: [PATCH 401/618] drm: convert drm_ioctl to unlocked_ioctl
drm_ioctl is called with the Big Kernel Lock held,
which shows up very high in statistics on vfs_ioctl.
Moving the lock into the drm_ioctl function itself
makes sure we blame the right subsystem and it gets
us one step closer to eliminating the locked version
of fops->ioctl.
Since drm_ioctl does not require the lock itself,
we only need to hold it while calling the specific
handler. The 32 bit conversion handlers do not
interact with any other code, so they don't need
the BKL here either and can just call drm_ioctl.
As a bonus, this cleans up all the other users
of drm_ioctl which now no longer have to find
the inode or call lock_kernel.
[airlied: squashed the non-driver bits
of the second patch in here, this provides
the flag for drivers to use to select unlocked
ioctls - but doesn't modify any drivers].

Subject: [PATCH 402/618] mm: Add notifier in pageblock isolation for balloon
drivers
Memory balloon drivers can allocate a large amount of memory which is not
movable but could be freed to accomodate memory hotplug remove.
Prior to calling the memory hotplug notifier chain the memory in the
pageblock is isolated. Currently, if the migrate type is not
MIGRATE_MOVABLE the isolation will not proceed, causing the memory removal
for that page range to fail.
Rather than failing pageblock isolation if the migrateteype is not
MIGRATE_MOVABLE, this patch checks if all of the pages in the pageblock,
and not on the LRU, are owned by a registered balloon driver (or other
entity) using a notifier chain. If all of the non-movable pages are owned
by a balloon, they can be freed later through the memory notifier chain
and the range can still be isolated in set_migratetype_isolate().

Subject: [PATCH 403/618] powerpc: Make the CMM memory hotplug aware
The Collaborative Memory Manager (CMM) module allocates individual pages
over time that are not migratable. On a long running system this can
severely impact the ability to find enough pages to support a hotplug
memory remove operation.
This patch adds a memory isolation notifier and a memory hotplug notifier.
The memory isolation notifier will return the number of pages found in
the range specified. This is used to determine if all of the used pages
in a pageblock are owned by the balloon (or other entities in the notifier
chain). The hotplug notifier will free pages in the range which is to be
removed. The priority of this hotplug notifier is low so that it will be
called near last, this helps avoids removing loaned pages in operations
that fail due to other handlers.
CMM activity will be halted when hotplug remove operations are active and
resume activity after a delay period to allow the hypervisor time to
adjust.

Subject: [PATCH 406/618] powerpc/pseries: Select XICS and PCI_MSI PSERIES
It's possible to set CONFIG_XICS without CONFIG_PCI_MSI. When that happens,
the kernel fails to build with
arch/powerpc/platforms/built-in.o: In function `.xics_startup':
xics.c:(.text+0x12f60): undefined reference to `.unmask_msi_irq' make: ***
[.tmp_vmlinux1] Error 1
Furthermore, as noted by Benjamin Herrenschmidt, "CONFIG_XICS should be
made invisible and selected by PSERIES."
This patch fixes PSERIES to select both options

acenic and cramfs modules
Machines with acenic adapters are rare these days, so we may as well make it
a module. Cramfs is also very rarely used so we can make it a module.
Together this saves 143kB on a 64bit compile:

Subject: [PATCH 409/618] powerpc/defconfigs: Set HZ=100 on pseries and ppc64
defconfigs
Now we have high res timers there is less of a reason for a high HZ value.
Furthermore I think there a few reasons we should reduce HZ to 100:
- Timer interrupt overhead. While this overhead is small, there are
applications that are very sensitive to jitter (eg some HPC apps).
- Issues with the timer wheel code. When coming out of NO_HZ idle we work our
way through the timer code one tick at a time. If we have been idle a long
time, this adds up - I sometimes see milliseconds of time spent in that
loop.
Long term we should fix the timer wheel algorithm, but for now if we reduce
HZ then we reduce the amount of work the timer code has to do when coming
out of idle.

since the later will perform checks with CONFIG_DEBUG_VM that aren't suitable
to the way we override an existing PTE. (More specifically, it doesn't let
you write over a present PTE).

If an online-attempt on a CPU which has been offlined using H_CEDE

Instead print the error message and let the __cpu_up() code notify the
CPU Hotplug framework of the failure, which in turn can notify the
other subsystem through CPU_UP_CANCELED.

The patch also makes the handlers clear the top 8 bytes of the register
when handling an 8 byte VSX load.
This is based on 2.6.32.

Subject: [PATCH 417/618] powerpc: Fix MSI support on U4 bridge PCIe slot
On machines using the Apple U4 bridge (AKA IBM CPC945) PCIe interface such
as the latest generation G5 machines x16 slot or the x16 slot of the
PowerStation, MSIs are currently broken (and will oops when enabling).
This fixes the oops and implements proper support for those. Instead of
using the PCIe <-> HT bridge conversion, on such slots we need to use
a bunch of magic registers in the bridge as the MSI target, encoding
the interrupt number in the low bits of the address itself

Subject: [PATCH 419/618] powerpc/mm: Fix stupid bug in subpge protection
handling
Commit d28513bc7f675d28b479db666d572e078ecf182d ("Fix bug in pagetable
cache cleanup with CONFIG_PPC_SUBPAGE_PROT"), itself a fix for
breakage caused by an earlier clean up patch of mine, contains a
stupid bug. I changed the parameters of the subpage_protection()
function, but failed to update one of the callers.
This patch fixes it, and replaces a void * with a typed pointer so
that the compiler will warn on such an error in future.

Since commit 57b150cce8e004ddd36330490a68bfb59b7271e9, desc->affinity
of an irq is changed after calling desc->chip->set_affinity.
Therefore we need to fix the irq_choose_cpu() not to depend on the
desc->affinity for new mask.

The retry logic in ug_putc() is broken.
If the TX fifo is not ready and the counter runs out it will have a
value of -1 and no transfer should be attempted. Also, a counter
with a value of 0 means that the TX fifo got ready in the last try
and the transfer should be attempted.

set_desc_affinity() is already checking if the incoming cpu mask
intersects with the cpu online mask or not. So there is no need
for the apic op cpu_mask_to_apicid_and() to check again
and return BAD_APICID.
Remove the BAD_APICID return value from cpu_mask_to_apicid_and()
and also fix set_desc_affinity() to return -1 instead of using BAD_APICID
to represent error conditions (as cpu_mask_to_apicid_and() can return
logical or physical apicid values and BAD_APICID is really to represent
bad physical apic id).

inotify_init1, preadv, pwritev and rt_tgsigqueueinfo syscalls for
the alpha port.
For umount2, alpha have an "old" and "new" version called: oldumount and
umount; so ignore umount2.

Subject: [PATCH 424/618] alpha: Add minimal support for software performance
events
In the kernel the patch enables configuration of the perf event
option, adds the perf_event_open syscall, and includes a minimal
architecture specific asm/perf_event.h header file.

Subject: [PATCH 427/618] sound: sgio2audio/pdaudiocf/usb-audio: initialize PCM
buffer
When allocating the PCM buffer, use vmalloc_user() instead of vmalloc().
Otherwise, it would be possible for applications to play the previous
contents of the kernel memory to the speakers, or to read it directly if
the buffer is exported to userspace.

Subject: [PATCH 428/618] hw-breakpoints: Fix hardware breakpoints -> perf
events dependency
The kbuild's select command doesn't propagate through the config
dependencies.
Hence the current rules of hardware breakpoint's config can't
ensure perf can never be disabled under us.
We have:
config X86
selects HAVE_HW_BREAKPOINTS
config HAVE_HW_BREAKPOINTS
select PERF_EVENTS
config PERF_EVENTS
[...]
x86 will select the breakpoints but that won't propagate to perf
events. The user can still disable the latter, but it is
necessary for the breakpoints.
What we need is:
- x86 selects HAVE_HW_BREAKPOINTS and PERF_EVENTS
- HAVE_HW_BREAKPOINTS depends on PERF_EVENTS
so that we ensure PERF_EVENTS is enabled and frozen for x86.
This fixes the following kind of build errors:
In file included from arch/x86/kernel/hw_breakpoint.c:31:
include/linux/hw_breakpoint.h: In function 'hw_breakpoint_addr':
include/linux/hw_breakpoint.h:39: error: 'struct perf_event' has no member named 'attr'
v2: Select also ANON_INODES from x86, required for perf

Subject: [PATCH 432/618] [S390] cio: fix drvdata usage for the console
subchannel
Using dev_set_drvdata prior to device_register will force the driver core
to kmalloc its private data. Since we use this for the console subchannel
lets set the drvdata before taking the subchannels spinlock.

Subject: [PATCH 433/618] [S390] dasd: move dasd-diag kmsg to dasd
The DIAG discipline does not have a own driver name. It shows up as
dasd-eckd or dasd-fba. So messages for dasd-diag are moved to the
generic dasd part.

Subject: [PATCH 440/618] [S390] cio: fix channel path vary
Channel path vary is currently broken: channel paths which are varied
offline are still used by Linux. The reason for this is that:
* the path mask indicating which paths of an I/O device can be used
is reset by each internal I/O request
* the logic that checks if a path group is already in its designated
target state incorrectly interprets the result "is correctly set"
as "is correctly set and available"
Fix this by resetting the path mask only for internal I/O requests
which affect the path mask and by correcting the pgid check logic.

WARN_ONs.
* Don't write debug feature log entries for sl, slsb and sbal since these
elements can be located from the qdio_q pointer which is also logged.
* Convert WARN_ON for wrong alignment of sbal to BUG_ON.
* Remove WARN_ON's for wrong alignment of q / qib / slib since these
alignments should be guaranteed by kmem_cache_alloc alignment /
struct aligned attribute / __get_free_page.

condition
Add a counter to the qdio performance statistics that indicates that no
free buffers were left in the input queue. If the counter gets increased
it means that the qdio adapter filled all available buffers and possibly
had more buffers ready but could not transmit them.

Subject: [PATCH 447/618] ALSA: AACI: simplify codec rate information
There's no need for a specific rule; ALSA's generic AC'97 support
calculates the necessary rate constraint information itself, and
we can use this directly.

Subject: [PATCH 452/618] ocfs2: Add reflinked file's inode to inode hash
eariler.
We used to add reflinked file's inode to inode hash when
we add it to the dest dir. But actually there is a race.
Consider the following sequence.
1. reflink happens and create the inode in orphan dir.
2. reflink thread is scheduled out because of some io.
3. recovery begins to work and calls ocfs2_recover_orphans.
It calls ocfs2_iget and get a new inode and i_count = 1.
It calls iput then and delete inode. the buffer's
uptodate state is cleared.
This patch move insert_inode_hash to the create function so
that it can be found by step 3 and prevented from deleting
because i_count > 1.
This resolves the bug

Subject: [PATCH 453/618] ocfs2: Set i_nlink properly during reflink.
We create a file in orphan dir for reflink so that if there
is any error, we don't create any wrong dentry in the dir.
But actually the file in orphan dir should be i_nlink = 0
so that it can be replayed and freed successfully.
This patch first set i_nlink to 0 when creating the file in
orphan dir and then set it to 1(reflink now only works for
regular file) when we move it to the dest dir.

Netxen driver is doing this bogus thing to create a control file.
This fails if device doesn't exist, and overall is a bad way to do
the module parameter. Rather than fix borked code, just rewrite.
Just using a writeable module parameter of 0/1 is the correct way

Alan Stern noticed that e100 caused slab corruption.
commit 98468efddb101f8a29af974101c17ba513b07be1 changed
the allocation of cbs to use dma pools that don't return zeroed memory,
especially the cb->status field used to track which cb to clean, causing
(the visible) double freeing of skbs and a wrong free cbs count.
Now the cbs are explicitly zeroed at allocation time.

It's because in ip6_frags_ns_sysctl_register,
"table" only alloced when "net" is not equals
to "init_net".So when we free "table" in
ip6_frags_ns_sysctl_unregister,we should check
this first.
This patch fix the problem.

If bnx2 schedules a reset via the reset_task, e.g., due to a TX
timeout, it's possible for the NIC to be disabled with packets
pending for transmit. In this case, napi_disable will loop forever,
eventually crashing the kernel. This patch moves the disable of
the device to after the napi_disable call.

Subject: [PATCH 463/618] can/at91: don't check platform_get_irq's return value
against zero
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
platform_get_irq returns -ENXIO on failure, so !irq was probably
always true. Better use (int)irq <= 0. Note that a return value of
zero is still handled as error even though this could mean irq0.
This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

Subject: [PATCH 466/618] gianfar: Fix stats support
This patch updates the per rx/tx queue stats.
To update the per rx queue stats a new structure has been
introduced rx_q_stats.
The per tx queue stats are updated via the netdev_queue
structure itself.
Note that we update only the tx_packtes, tx_bytes, rx_packets,
rx_bytes and rx_dropped stats on a per queue basis.

Subject: [PATCH 469/618] fix braindamage in audit_tree.c untag_chunk()
... aka "Al had badly fscked up when writing that thing and nobody
noticed until Eric had fixed leaks that used to mask the breakage".
The function essentially creates a copy of old array sans one element
and replaces the references to elements of original (they are on cyclic
lists) with those to corresponding elements of new one. After that the
old one is fair game for freeing.
First of all, there's a dumb braino: when we get to list_replace_init we
use indices for wrong arrays - position in new one with the old array
and vice versa.
Another bug is more subtle - termination condition is wrong if the
element to be excluded happens to be the last one. We shouldn't go
until we fill the new array, we should go until we'd finished the old
one. Otherwise the element we are trying to kill will remain on the
cyclic lists...
That crap used to be masked by several leaks, so it was not quite
trivial to hit. Eric had fixed some of those leaks a while ago and the
shit had hit the fan...

It's dumb and causes stupid "sched: " strings all over the place.

Subject: [PATCH 473/618] Revert "pata_cmd64x: implement serialization as per
notes"
This reverts commit d43744390e460dce6626fb8de2c02a24ff650005, because
it breaks the boot on several machines (mostly sparc64, at present).

Date: Sun, 20 Dec 2009 19:22:33 +0100
Subject: [PATCH 474/618] pata_cmd64x: fix overclocking of UDMA0-2 modes
adev->dma_mode stores the transfer mode value not UDMA mode number
so the condition in cmd64x_set_dmamode() is always true and the higher
UDMA clock is always selected. This can potentially result in data
corruption when UDMA33 device is used, when 40-wire cable is used or
when the error recovery code decides to lower the device speed down.
The issue was introduced in the commit 6a40da0 ("libata cmd64x: whack
into a shape that looks like the documentation") which goes back to
kernel 2.6.20.

arch/powerpc/platforms/embedded6xx/hlwd-pic.c:135: error: passing argument 1 of 'spin_lock' from incompatible pointer type

arch/powerpc/platforms/embedded6xx/hlwd-pic.c:149: error: passing argument 1 of 'spin_unlock' from incompatible pointer type
These failures are caused by the changes introduced in commit
"genirq: Convert irq_desc.lock to raw_spinlock". The reason this driver
was not updated is that it wasn't merged yet.

arch/powerpc/platforms/embedded6xx/flipper-pic.c: In function 'flipper_pic_map':
arch/powerpc/platforms/embedded6xx/flipper-pic.c:105: error: implicit declaration of function 'get_irq_desc'
arch/powerpc/platforms/embedded6xx/hlwd-pic.c: In function 'hlwd_pic_map':
arch/powerpc/platforms/embedded6xx/hlwd-pic.c:98: error: implicit declaration of function 'get_irq_desc'
These failures are caused by the changes introduced in commit
"powerpc: Remove get_irq_desc()". The reason these drivers were not
updated is that they weren't merged yet.

Subject: [PATCH 478/618] PM: Use pm_runtime_put_sync in system resume
This patch (as1317) fixes a bug in the PM core. When a device is
resumed following a system sleep, the core decrements the device's
runtime PM usage counter but doesn't issue an idle notification if the
counter reaches 0. This could prevent an otherwise unused device from
being runtime-suspended again after the system sleep.
The fix is to call pm_runtime_put_sync() instead of
pm_runtime_put_noidle().

Subject: [PATCH 484/618] ALSA: HDA: add powersaving hook for Realtek
The current Realtek code makes no specific provision for turning stuff
off. The codec chip is placed into low-power mode generically, but this
doesn't turn off any external hardware connected to it, in particular
external amplifiers.
This patch creates a hook function that is called by the codec
suspend/resume functions. It ought to disable any external hardware in a
device-specific way. I've implemented a generic ALC889 function that
sets the EAPD pin properly, and used it for the Acer Aspire 8930G which
can benefit from this feature.
On my laptop, this results in ~0.5W extra savings.

Subject: [PATCH 485/618] ALSA: fix incorrect rounding direction in
snd_interval_ratnum()
The direction of rounding is incorrect in the snd_interval_ratnum()
It was detected with following parameters (sb8 driver playing
8kHz stereo file):
- num is always 1000000
- requested frequency rate is from 7999 to 7999 (single frequency)
The first loop calculates div_down(num, freq->min) which is 125.
Thus, a frequency range's minimum value is 1000000 / 125 = 8000 Hz.
The second loop calculates div_up(num, freq->max) which is 126
The frequency range's maximum value is 1000000 / 126 = 7936 Hz.
The range maximum is lower than the range minimum so the function
fails due to empty result range.

Subject: [PATCH 487/618] resources: fix call to alignf() in
allocate_resource()
The second parameter to alignf() in allocate_resource() must
reflect what new resource is attempted to be allocated, else
functions like pcibios_align_resource() (at least on x86) or
pcmcia_align() can't work correctly.
Commit 1e5ad9679016275d422e36b12a98b0927d76f556 broke this by
setting the "new" resource until we're about to return success.
To keep the resource untouched when allocate_resource() fails,
a "tmp" resource is introduced.

By default, the PATA pins are routed to the async address lines in which
case, no peripheral muxing needs to be done. However, if the pins get
routed through the GPIO PORTs pins, we need to make sure to request them
so that the muxing is properly set up.

platform_get_irq returns -ENXIO on failure, so !irq was probably
always true. Better use (int)irq <= 0. Note that a return value of
zero is still handled as error even though this could mean irq0.
This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

When alloc_file() and init_file() were combined, the error handling of
mnt_clone_write() was taken into alloc_file() in a somewhat obfuscated
way. Since we don't use the error code for anything except warning,
we might as well warn directly without an extra variable.

Subject: [PATCH 498/618] fs/compat_ioctl.c: fix build error when !BLOCK
No driver uses SG_SET_TRANSFORM any more in Linux, since the ide-scsi
driver was removed in 2.6.29. The compat-ioctl cleanup series moved
the handling for this around, which broke building without CONFIG_BLOCK.
Just remove the code handling it for compat mode.

Subject: [PATCH 499/618] anonfd: Allow making anon files read-only
It seems a couple places such as arch/ia64/kernel/perfmon.c and
drivers/infiniband/core/uverbs_main.c could use anon_inode_getfile()
instead of a private pseudo-fs + alloc_file(), if only there were a way
to get a read-only file. So provide this by having anon_inode_getfile()
create a read-only file if we pass O_RDONLY in flags.

Subject: [PATCH 500/618] Fix f_flags/f_mode in case of
lookup_instantiate_filp() from open(pathname, 3)
Just set f_flags when shoving struct file into nameidata; don't
postpone that until __dentry_open(). do_filp_open() has correct
value; lookup_instantiate_filp() doesn't - we lose the difference
between O_RDWR and 3 by that point.
We still set .intent.open.flags, so no fs code needs to be changed.

Subject: [PATCH 504/618] PM / Runtime: Use device type and device class
callbacks
The power management of some devices is handled through device types
and device classes rather than through bus types. Since these
devices may also benefit from using the run-time power management
core, extend it so that the device type and device class run-time PM
callbacks can be taken into consideration by it if the bus type
callback is not defined.
Update the run-time PM core documentation to reflect this change.

+
+6. Run-time PM and System Sleep
+
+Run-time PM and system sleep (i.e., system suspend and hibernation, also known
+as suspend-to-RAM and suspend-to-disk) interact with each other in a couple of
+ways. If a device is active when a system sleep starts, everything is
+straightforward. But what should happen if the device is already suspended?
+
+The device may have different wake-up settings for run-time PM and system sleep.
+For example, remote wake-up may be enabled for run-time suspend but disallowed
+for system sleep (device_may_wakeup(dev) returns 'false'). When this happens,
+the subsystem-level system suspend callback is responsible for changing the
+device's wake-up setting (it may leave that to the device driver's system
+suspend routine). It may be necessary to resume the device and suspend it again
+in order to do so. The same is true if the driver uses different power levels
+or other settings for run-time suspend and system sleep.
+
+During system resume, devices generally should be brought back to full power,
+even if they were suspended before the system sleep began. There are several
+reasons for this, including:
+
+ * The device might need to switch power levels, wake-up settings, etc.
+
+ * Remote wake-up events might have been lost by the firmware.
+
+ * The device's children may need the device to be at full power in order
+ to resume themselves.
+
+ * The driver's idea of the device state may not agree with the device's
+ physical state. This can happen during resume from hibernation.
+
+ * The device might need to be reset.
+
+ * Even though the device was suspended, if its usage counter was > 0 then most
+ likely it would need a run-time resume in the near future anyway.
+
+ * Always going back to full power is simplest.
+
+If the device was suspended before the sleep began, then its run-time PM status
+will have to be updated to reflect the actual post-system sleep status. The way
+to do this is:
+
+ pm_runtime_disable(dev);
+ pm_runtime_set_active(dev);
+ pm_runtime_enable(dev);
+
+The PM core always increments the run-time usage counter before calling the
+->prepare() callback and decrements it after calling the ->complete() callback.
+Hence disabling run-time PM temporarily like this will not cause any run-time
+suspend callbacks to be lost.

Subject: [PATCH 506/618] Revert "time: Remove xtime_cache"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This reverts commit 7bc7d637452383d56ba4368d4336b0dde1bb476d, as
requested by John Stultz. Quoting John:
"Petr Titěra reported an issue where he saw odd atime regressions with
2.6.33 where there were a full second worth of nanoseconds in the
nanoseconds field.
He also reviewed the time code and narrowed down the problem: unhandled
overflow of the nanosecond field caused by rounding up the
sub-nanosecond accumulated time.
Details:
* At the end of update_wall_time(), we currently round up the
sub-nanosecond portion of accumulated time when storing it into xtime.
This was added to avoid time inconsistencies caused when the
sub-nanosecond portion was truncated when storing into xtime.
Unfortunately we don't handle the possible second overflow caused by
that rounding.
* Previously the xtime_cache code hid this overflow by normalizing the
xtime value when storing into the xtime_cache.
* We could try to handle the second overflow after the rounding up, but
since this affects the timekeeping's internal state, this would further
complicate the next accumulation cycle, causing small errors in ntp
steering. As much as I'd like to get rid of it, the xtime_cache code is
known to work.
* The correct fix is really to include the sub-nanosecond portion in the
timekeeping accessor function, so we don't need to round up at during
accumulation. This would greatly simplify the accumulation code.
Unfortunately, we can't do this safely until the last three
non-GENERIC_TIME arches (sparc32, arm, cris) are converted (those
patches are in -mm) and we kill off the spots where arches set xtime
directly. This is all 2.6.34 material, so I think reverting the
xtime_cache change is the best approach for now.
Many thanks to Petr for both reporting and finding the issue!"

Subject: [PATCH 509/618] kfifo: move struct kfifo in place
This is a new generic kernel FIFO implementation.
The current kernel fifo API is not very widely used, because it has to
many constrains. Only 17 files in the current 2.6.31-rc5 used it.
FIFO's are like list's a very basic thing and a kfifo API which handles
the most use case would save a lot of development time and memory
resources.
I think this are the reasons why kfifo is not in use:
- The API is to simple, important functions are missing
- A fifo can be only allocated dynamically
- There is a requirement of a spinlock whether you need it or not
- There is no support for data records inside a fifo
So I decided to extend the kfifo in a more generic way without blowing up
the API to much. The new API has the following benefits:
- Generic usage: For kernel internal use and/or device driver.
- Provide an API for the most use case.
- Slim API: The whole API provides 25 functions.
- Linux style habit.
- DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros
- Direct copy_to_user from the fifo and copy_from_user into the fifo.
- The kfifo itself is an in place member of the using data structure, this save an
indirection access and does not waste the kernel allocator.
- Lockless access: if only one reader and one writer is active on the fifo,
which is the common use case, no additional locking is necessary.
- Remove spinlock - give the user the freedom of choice what kind of locking to use if
one is required.
- Ability to handle records. Three type of records are supported:
- Variable length records between 0-255 bytes, with a record size
field of 1 bytes.
- Variable length records between 0-65535 bytes, with a record size
field of 2 bytes.
- Fixed size records, which no record size field.
- Preserve memory resource.
- Performance!
- Easy to use!
This patch:
Since most users want to have the kfifo as part of another object,
reorganize the code to allow including struct kfifo in another data
structure. This requires changing the kfifo_alloc and kfifo_init
prototypes so that we pass an existing kfifo pointer into them. This
patch changes the implementation and all existing users.

From c1e13f25674ed564948ecb7dfe5f83e578892896 Mon Sep 17 00:00:00 2001
From: Stefani Seibold <stefani@seibold.net>
Date: Mon, 21 Dec 2009 14:37:27 -0800
Subject: [PATCH 510/618] kfifo: move out spinlock
Move the pointer to the spinlock out of struct kfifo. Most users in
tree do not actually use a spinlock, so the few exceptions now have to
call kfifo_{get,put}_locked, which takes an extra argument to a
spinlock.

From: Stefani Seibold <stefani@seibold.net>
Date: Mon, 21 Dec 2009 14:37:28 -0800
Subject: [PATCH 511/618] kfifo: cleanup namespace
change name of __kfifo_* functions to kfifo_*, because the prefix __kfifo
should be reserved for internal functions only.

From 7acd72eb85f1c7a15e8b5eb554994949241737f1 Mon Sep 17 00:00:00 2001
From: Stefani Seibold <stefani@seibold.net>
Date: Mon, 21 Dec 2009 14:37:28 -0800
Subject: [PATCH 512/618] kfifo: rename kfifo_put... into kfifo_in... and
kfifo_get... into kfifo_out...
rename kfifo_put... into kfifo_in... to prevent miss use of old non in
kernel-tree drivers
ditto for kfifo_get... -> kfifo_out...
Improve the prototypes of kfifo_in and kfifo_out to make the kerneldoc
annotations more readable.
Add mini "howto porting to the new API" in kfifo.h

Subject: [PATCH 513/618] kfifo: fix warn_unused_result
Fix the "ignoring return value of '...', declared with attribute
warn_unused_result" compiler warning in several users of the new kfifo
API.
It removes the __must_check attribute from kfifo_in() and
kfifo_in_locked() which must not necessary performed.
Fix the allocation bug in the nozomi driver file, by moving out the
kfifo_alloc from the interrupt handler into the probe function.
Fix the kfifo_out() and kfifo_out_locked() users to handle a unexpected
end of fifo.

From: Stefani Seibold <stefani@seibold.net>
Date: Mon, 21 Dec 2009 14:37:32 -0800
Subject: [PATCH 516/618] kfifo: add record handling functions
Add kfifo_in_rec() - puts some record data into the FIFO
Add kfifo_out_rec() - gets some record data from the FIFO
Add kfifo_from_user_rec() - puts some data from user space into the FIFO
Add kfifo_to_user_rec() - gets data from the FIFO and write it to user space
Add kfifo_peek_rec() - gets the size of the next FIFO record field
Add kfifo_skip_rec() - skip the next fifo out record
Add kfifo_avail_rec() - determinate the number of bytes available in a record FIFO

Subject: [PATCH 517/618] media video cx23888 driver: ported to new kfifo API
Fix the cx23888 driver to use the new kfifo API. Using kfifo_reset()
may result in a possible race conditions. This patch fixes it by using
a spinlock around the kfifo_reset() function.

Subject: [PATCH 518/618] DRM: Rename clamp variable
linux/kernel.h has a "clamp" macro, but r300_cmdbuf also uses a variable
with the same name. Right now it doesn't seem to include the header,
but sooner or later someone will. So better rename the variable
now.

Use kzalloc rather than kcalloc(1,...)
The use of the allocated memory that looks like an array is &p->relocs[0],
but this should be the same as p->relocs.
The semantic patch that makes this change is as follows:

From 7a73ba7469cbea631050094fd14f73acebb97cf9 Mon Sep 17 00:00:00 2001
From: Thomas Hellstrom <thellstrom@vmware.com>
Date: Tue, 22 Dec 2009 16:53:41 +0100
Subject: [PATCH 523/618] drm/vmwgfx: Use TTM handles instead of SIDs as
user-space surface handles.
Improve the command verifier to catch all occurences of surface handles,
and translate to SIDs.
This way DMA buffers and 3D surfaces share a common handle space,
which makes it possible for the kms code to differentiate.

Subject: [PATCH 531/618] drm/radeon/kms: allow rendering while no colorbuffer
is set on r300
Because hardware cannot disable all colorbuffers directly to do depth-only
rendering, a user should:
- disable reading from a colorbuffer in blending
- disable fastfill
- set the color channel mask to 0 to prevent writing to a colorbuffer

Subject: [PATCH 533/618] drm/radeon/kms: add cvt mode if we only have lvds w/h
and no edid (v4)
This fixes LVDS on some mac laptops without a panel edid.
v2 - Set proper mode type flags
v3 - Note that this is not neceesarily the exact panel mode,
but an approximation based on the cvt formula. For these
systems we should ideally read the mode info out of the
registers or add a mode table, but this works and is much
simpler.
v4 - Update comments and debug message.

Subject: [PATCH 539/618] sched: Revert 738d2be, simplify set_task_cpu()
Effectively reverts 738d2be4301007f054541c5c4bf7fb6a361c9b3a.
As demonstrated by Eric, we really need to call __set_task_cpu()
early in the fork() path to properly initialize the various task
state -- specifically the cgroup state through set_task_rq().
[ we could probably fix this by explicitly calling
__set_task_cpu() from sched_fork(), but lets try that for the
next cycle and simply revert to the old behaviour for now. ]

Currently all quota block reservation macros contains hardcoded "2"
aka MAXQUOTAS value. This is no good because in some places it is not
obvious to understand what does this digit represent. Let's introduce
new macro with self descriptive name.

Subject: [PATCH 541/618] Add unlocked version of inode_add_bytes() function
Quota code requires unlocked version of this function. Off course
we can just copy-paste the code, but copy-pasting is always an evil.

Subject: [PATCH 542/618] quota: decouple fs reserved space from quota
reservation
Currently inode_reservation is managed by fs itself and this
reservation is transfered on dquot_transfer(). This means what
inode_reservation must always be in sync with
dquot->dq_dqb.dqb_rsvspace. Otherwise dquot_transfer() will result
in incorrect quota(WARN_ON in dquot_claim_reserved_space() will be
triggered)
This is not easy because of complex locking order issues
for example http://bugzilla.kernel.org/show_bug.cgi?id=14739
The patch introduce quota reservation field for each fs-inode
(fs specific inode is used in order to prevent bloating generic
vfs inode). This reservation is managed by quota code internally
similar to i_blocks/i_bytes and may not be always in sync with
internal fs reservation.
Also perform some code rearrangement:
- Unify dquot_reserve_space() and dquot_reserve_space()
- Unify dquot_release_reserved_space() and dquot_free_space()
- Also this patch add missing warning update to release_rsv()
dquot_release_reserved_space() must call flush_warnings() as
dquot_free_space() does.

Subject: [PATCH 545/618] ext3: Remove outdated comment about lock_super()
ext3_fill_super() is no longer called by read_super(), and it is no
longer called with the superblock locked. The
unlock_super()/lock_super() is no longer present, so this comment is
entirely superfluous.

Subject: [PATCH 546/618] ext3: ext3_mark_recovery_complete() doesn't need to
use lock_super
The function ext3_mark_recovery_complete() is called from two call
paths: either (a) while mounting the filesystem, in which case there's
no danger of any other CPU calling write_super() until the mount is
completed, and (b) while remounting the filesystem read-write, in
which case the fs core has already locked the superblock. This also
allows us to take out a very vile unlock_super()/lock_super() pair in
ext3_remount().

Subject: [PATCH 554/618] ASoC: Do not write to invalid registers on the
wm9712.
This patch fixes a bug where "virtual" registers were being written to the ac97
bus. This was causing unrelated registers to become corrupted (headphone 0x04,
touchscreen 0x78, etc).
This patch duplicates protection that was included in the wm9713 driver.

Subject: [PATCH 556/618] kfifo: fix Error/broken kernel-doc notation
Fix kernel-doc errors and warnings in new header file kfifo.h.
Don't use kernel-doc "/**" for internal functions whose comments
are not in kernel-doc format.
kernel-doc section header names (like "Note:") must be unique
per function. Looks like I need to document that.
Error(include/linux/kfifo.h:76): duplicate section name 'Note'
Warning(include/linux/kfifo.h:88): Excess function parameter 'size' description in 'INIT_KFIFO'
Error(include/linux/kfifo.h:101): duplicate section name 'Note'
Warning(include/linux/kfifo.h:257): No description found for parameter 'fifo'
(many of this last type, from internal functions)

Subject: [PATCH 558/618] devtmpfs: Convert dirlock to a mutex
devtmpfs has a rw_lock dirlock which serializes delete_path and
create_path.
This code was obviously never tested with the usual set of debugging
facilities enabled. In the dirlock held sections the code calls:
- vfs functions which take mutexes
- kmalloc(, GFP_KERNEL)
In both code pathes the might sleep warning triggers and spams dmesg.
Convert the rw_lock to a mutex. There is no reason why this needs to
be a rwlock.

Subject: [PATCH 559/618] vfs: get_sb_single() - do not pass options twice
Filesystem code usually destroys the option buffer while
parsing it. This leads to errors when the same buffer is
passed twice. In case we fill a new superblock do not call
remount.
This is needed to quite a warning that the debugfs code
causes every boot.

Subject: [PATCH 563/618] Driver core: driver_attribute parameters can often be
const*
Many struct driver_attribute descriptors are purely read-only
structures, and there's no need to change them. Therefore make
the promise not to, which will let those descriptors be put in
a ro section.

Subject: [PATCH 564/618] Driver-core: Fix bogus 0 error return in device_add()
If device_add() is called with a device which does not have dev->p set
up, then device_private_init() is called. If that succeeds, then the
error variable is set to 0. Now if the dev_name(dev) check further
down fails, then device_add() correctly terminates, but returns 0.
That of course lets the driver progress. If later another driver uses
this half set up device as parent then device_add() of the child
device explodes and renders sysfs completely unusable.
Set the error to -EINVAL if dev_name() check fails.

Subject: [PATCH 568/618] Staging: sm7xx: add a new framebuffer driver
Yeeloong netbook has a sm712 video card, need this driver, but it is not
ready to upstream yet, so, go to drivers/staing at first.
This source code is originally from Silicon Motion Technology Corp, and
maintained at http://dev.lemote.com/code/linux_loongson for YeeLoong
netbook. I have done a lot of cleanups for it and merged it into my git
repository at http://dev.lemote.com/code/rt4ls.
Thanks to Simon for testing it on a little-endian x86 platform.
Thanks to Olivier Croset <olivier.croset@actis-computer.com> for
reporting the problem about __BIG_ENDIAN compiling problem and send a
relative patch.
The suspend/resume and blank support are contributed by Jason from
Silicon Motion Technology.

Subject: [PATCH 569/618] Staging: dst: remove from the tree
DST is dead, no one is using it and upstream
has abandoned it, so remove it from the tree because
it is not going anywhere.

-config DST
- tristate "Distributed storage"
- depends on NET && CRYPTO && SYSFS && BLK_DEV
- select CONNECTOR
- ---help---
- DST is a network block device storage, which can be used to organize
- exported storage on the remote nodes into the local block device.
-
- DST works on top of any network media and protocol; it is just a matter
- of configuration utility to understand the correct addresses. The most
- common example is TCP over IP, which allows to pass through firewalls and
- create remote backup storage in a different datacenter. DST requires
- single port to be enabled on the exporting node and outgoing connections
- on the local node.
-
- DST works with in-kernel client and server, which improves performance by
- eliminating unneded data copies and by not depending on the version
- of the external IO components. It requires userspace configuration utility
- though.
-
- DST uses transaction model, when each store has to be explicitly acked
- from the remote node to be considered as successfully written. There
- may be lots of in-flight transactions. When remote host does not ack
- the transaction it will be resent predefined number of times with specified
- timeouts between them. All those parameters are configurable. Transactions
- are marked as failed after all resends complete unsuccessfully; having
- long enough resend timeout and/or large number of resends allows not to
- return error to the higher (FS usually) layer in case of short network
- problems or remote node outages. In case of network RAID setup this means
- that storage will not degrade until transactions are marked as failed, and
- thus will not force checksum recalculation and data rebuild. In case of
- connection failure DST will try to reconnect to the remote node automatically.
- DST sends ping commands at idle time to detect if remote node is alive.
-
- Because of transactional model it is possible to use zero-copy sending
- without worry of data corruption (which in turn could be detected by the
- strong checksums though).
-
- DST may fully encrypt the data channel in case of untrusted channel and implement
- strong checksum of the transferred data. It is possible to configure algorithms
- and crypto keys; they should match on both sides of the network channel.
- Crypto processing does not introduce noticeble performance overhead, since DST
- uses configurable pool of threads to perform crypto processing.
-
- DST utilizes memory pool model of all its transaction allocations (it is the
- only additional allocation on the client) and server allocations (bio pools,
- while pages are allocated from the slab).
-
- At startup DST performs a simple negotiation with the export node to determine
- access permissions and size of the exported storage. It can be extended if
- new parameters should be autonegotiated.
-
- DST carries block IO flags in the protocol, which allows to transparently implement
- barriers and sync/flush operations. Those flags are used in the export node where
- IO against the local storage is performed, which means that sync write will be sync
- on the remote node too, which in turn improves data integrity and improved resistance
- to errors and data corruption during power outages or storage damages.

Subject: [PATCH 570/618] Staging: comedi: usbdux.c: fix locking up of the
driver when the comedi ringbuffer runs empty
Jan-Matthias Braun spotted a bug which locks up the driver when the
comedi ring buffer runs empty and provided a patch. The driver would
still send the data to comedi but the reader won't wake up any more.
What's required is setting the flag COMEDI_CB_BLOCK after new data has
arrived which wakes up the reader and therefore the read() command.

COMEDI_CB_BLOCK
The flag COMEDI_CB_BLOCK was marked as "depricated in the header file".
However, this flag is important to wake up the data-reader (and writer)
after new data has arrived from(for) the DAQ card.

For the JR3/PCI cards, the size of the PCIBAR0 region depends on the

card has fewer channels. Also check for ioremap failure.

Subject: [PATCH 588/618] USB: fix bugs in usb_(de)authorize_device
This patch (as1315) fixes some bugs in the USB core authorization
code:
usb_deauthorize_device() should deallocate the device strings
instead of leaking them, and it should invoke
usb_destroy_configuration() (which does proper reference
counting) instead of freeing the config information directly.
usb_authorize_device() shouldn't change the device strings
until it knows that the authorization will succeed, and it should
autosuspend the device at the end (having autoresumed the
device at the start).
Because the device strings can be changed, the sysfs routines
to display the strings must protect the string pointers by
locking the device.

Subject: [PATCH 592/618] USB: emi62: fix crash when trying to load EMI 6|2
firmware
While converting emi62 to use request_firmware(), the driver was also
changed to use the ihex helper functions. However, this broke the loading
of the FPGA firmware because the code tries to access the addr field of
the EOF record which works with a plain array that has an empty last
record but not with the ihex helper functions where the end of the data is
signaled with a NULL record pointer, resulting in:
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62]
This can be fixed by changing the loop condition to test the return value
of ihex_next_binrec() directly (like in emi26.c).

This is a strictly move-only patch to relocate all FTDI device
product ID definitions to their own ftdi_sio_ids.h header
(following the usual *_ids.h kernel tree convention, too),
thus correcting the slightly too messy appearance
(crucial driver defines were stuck somewhere in the decaying middle swamp
of the huge existing header).
Compile-tested, based on latest mainline git.

From 4e092d110fe931db3878865db185be1c9df3e182 Mon Sep 17 00:00:00 2001
From: Andreas Mohr <andi@lisas.de>
Date: Thu, 17 Dec 2009 11:56:09 +0100
Subject: [PATCH 597/618] USB: ftdi_sio: sort PID/VID entries in new
ftdi_sio_ids.h header
This is a (almost) sort-only patch to sort FTDI device
product ID definitions in new ftdi_sio_ids.h header.
Advantage is that new device ID submissions will now have a specific (sorted)
position - less future merge conflicts.
Compile-tested, based on _current_ mainline git.
Minor checkpatch.pl warnings were eliminated whereever it made sense,
very minor text changes.

Subject: [PATCH 605/618] USB: musb: fix for crash in DM646x USB when (CPPI)DMA
is enabled
Race condition exists between the cppi_interrupt handler and
davinci_interrupt handler w.r.t completing a TX IO. Since DM646x
has seperate DMA and USB endpoint interrupts cppi_interrupt handler
needs to hold the lock while operating on the endpoint.
Update over previous patch to avoid taking the lock if already
taken. Tested on DM644x, DM355 and DM646x platforms.

Subject: [PATCH 609/618] USB: musb: Fix array index out of bounds issue
This patch fixes the below array index out of bounds issue.
Buffer overflow, array index of 'aInfo' may be out of
bounds. Array 'aInfo' of size 78 may use index value(s) 6..84
The data stored in 'aInfo' array exceeds the array size of 78.
This patch increases the size of this array to hold the string
correctly without any memory corruption.
This issue was reported by Klockwork tool.

Subject: [PATCH 610/618] USB: musb: workaround Blackfin FIFO anomalies
Some of these workarounds are already in place, but labeled as affecting
all BF52x parts. Since we have official anomaly numbers now, use those
defines. And since writing to the FIFO has a similar hang issue as reading
from the FIFO, implement the workaround there too when necessary.

I made this patch for usbserial driver to add the support for EVDO modem
Haier CE100. The bugs report for this is here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/490068
This patch based on these post:

Subject: [PATCH 615/618] USB: Fix a bug on appledisplay.c regarding signedness
brightness status is reported by the Apple Cinema Displays as an
'unsigned char' (u8) value, but the code used 'char' instead.
Note that he driver was developed on the PowerPC architecture,
where the two types are synonymous, which is not always the case.
Fixed that. Otherwise the driver will interpret brightness
levels > 127 as negative, and fail to load.

Subject: [PATCH 616/618] Revert "x86, ucode-amd: Ensure ucode update on
suspend/resume after CPU off/online cycle"
This reverts commit 9f15226e75583547aaf542c6be4bdac1060dd425. It's just
wrong, and broke resume for Rafael even on a non-AMD CPU.
As Rafael says:
"... it causes microcode_init_cpu() to be called during resume even for
CPUs for which there's no microcode to apply. That, in turn, results
in executing request_firmware() (on Intel CPUs at least) which doesn't
work at this stage of resume (we have device interrupts disabled, I/O
devices are still suspended and so on).
If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is
known to us" , so before commit 9f15226e755 microcode_resume_cpu() was
called for all CPUs already in the system during suspend, which was
the right thing to do. The commit changed it so that the CPUs without
microcode to apply are now treated as "unknown", which is not quite
right.
The problem this commit attempted to solve has to be handled
differently."

Subject: [PATCH 618/618] serial: sh-sci: Convert tremaining ctrl_xxx I/O
routines to __raw_xxx.
ctrl_xxx() is an antiquated SH interface, while __raw_xxx is the standard
API that accomplishes the same thing. As such, this converts the
remaining sh-sci straggles over, which enables the driver to be wired up
for ARM SH-Mobile CPUs as well.
