      localmodconfig: Document localmodconfig in README · 80b810b2
      Steven Rostedt authored
      Someone (over a year ago :-p) asked me to document localmodconfig in the
      README file in the source code.  I thought it was a good idea but other
      things were more important and I simply forgot about it.  Well, I
      stumbled on the email asking me about this and I'm sending it out now.

      Pull ext4 updates from Ted Ts'o:
       "The big new feature added this time is supporting online resizing
        using the meta_bg feature.  This allows us to resize file systems
        which are greater than 16TB.  In addition, the speed of online
        resizing has been improved in general.
        We also fix a number of races, some of which could lead to deadlocks,
        in ext4's Asynchronous I/O and online defrag support, thanks to good
        work by Dmitry Monakhov.

       "This is the first chunk of ARM updates for this merge window.

        mach-integrator/integrator_cp.c.  Nothing particularly stands out more
        than anything else.
        Most of the growth is down to the opcodes stuff from Dave Martin,

        headers on ARM."

      Pull late ARM soc platform updates from Olof Johansson:
       "This branch contains updates to OMAP and Marvell platforms (kirkwood,
        dove, mvebu) that came in after we had done the big multiplatform
        merges, so they were kept separate from the rest, and not separated
        into the traditional topics of cleanup/driver/platform features.
        For OMAP, the updates are:
         - Runtime PM conversions for the GPMC and RNG IP blocks
         - Preparation patches for the OMAP common clock framework conversion
         - clkdev alias additions required by other drivers
         - Performance Monitoring Unit (PMU) support for OMAP2, 3, and
           non-4430 OMAP4
         - OMAP hwmod code and data improvements
         - Preparation patches for the IOMMU runtime PM conversion
         - Preparation patches for OMAP4 full-chip retention support
        For Kirkwood/Dove/mvebu:
         - New driver for "address decoder controller" for mvebu, which is a
           piece of hardware that configures addressable devices and
           peripherals.  First user is the boot rom aperture on armada XP
           since it is needed for SMP support.
         - New device tree bindings for peripherals such as gpio-fan, iconnect
           nand, mv_cesa and the above address decoder controller.
         - Some defconfig updates, mostly to enable new DT boards and a few
         - New drivers using the pincontrol subsystem for dove, kirkwood and
         - New clean gpio driver for mvebu"

      Pull media updates from Mauro Carvalho Chehab:
       "The first part of the media updates for Kernel 3.7.
        This series contain:
         - A major tree renaming patch series: now, drivers are organized
           internally by their used bus, instead of by V4L2 and/or DVB API,
           providing a cleaner driver location for hybrid drivers that
           implement both APIs, and allowing to cleanup the Kconfig items and
           make them more intuitive for the end user;
         - Media Kernel developers are typically very lazy with their duties
           of keeping the MAINTAINERS entries for their drivers updated.  As
           now the tree is more organized, we're doing an effort to add/update
           those entries for the drivers that aren't currently orphan;
         - Several DVB USB drivers got moved to a new DVB USB v2 core; the new
           core fixes several bugs (as the existing one that got bitroted).
           Now, suspend/resume finally started to work fine (at least with
           some devices - we should expect more work with regards to it);
         - added multistream support for DVB-T2, and unified the API for
           DVB-S2 and ISDB-S.  Backward binary support is preserved;
         - as usual, a few new drivers, some V4L2 core improvements and lots
           of drivers improvements and fixes.
        There are some points to notice on this series:
         1) you should expect a trivial merge conflict on your tree, with the
            removal of Documentation/feature-removal-schedule.txt: this series
            would be adding two additional entries there.  I opted to not
            rebase it due to this recent change;
         2) With regards to the PCTV 520e udev-related breakage, I opted to
            fix it in a way that the patches can be backported to 3.5 even
            without your firmware fix patch.  This way, Greg doesn't need to
            rush backporting your patch (as there are still the firmware cache
            and firmware path customization issues to be addressed there).
            I'll send later a patch (likely after the end of the merge window)
            reverting the rest of the DRX-K async firmware request, fully
            restoring its original behaviour to allow media drivers to
            initialize everything serialized as before for 3.7 and upper.
         3) I'm planning to work on this weekend to test the DMABUF patches
            for V4L2.  The patches are on my queue for several Kernel cycles,
            but, up to now, there is/was no way to test the series locally.
            I have some concerns about this particular changeset with regards
            to security issues, and with regards to the replacement of the old
            VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
            GPU drivers change.  The Overlay API allows direct PCI2PCI
            transfers from a media capture card into the GPU framebuffer, but
            its API is crappy.  Also, the only existing X11 driver that
            implements it requires a XV extension that is not available
            anymore on modern drivers.  The DMABUF can do the same thing, but
            with it is promising to be a properly-designed API.  If I can
            successfully test this series and be happy with it, I should be
            asking you to pull them next week."

      Pull UAPI disintegration fixes from David Howells:
       "There are three main parts:
       (1) I found I needed some more fixups in the wake of testing Arm64
           (some asm/unistd.h files had weird guards that caused problems -
           mostly in arches for which I don't have a compiler) and some
           __KERNEL__ splitting needed to take place in Arm64.
       (2) I found that c6x was missing some __KERNEL__ guards in its
           asm/signal.h.  Mark Salter pointed me at a tree with a patch to
           remove that file entirely and use the asm-generic variant instead.
       (3) Lastly, m68k turned out to have a header installation problem due
           to it lacking a kvm_para.h file.
           The conditional installation bits for linux/kvm_para.h, linux/kvm.h
           and linux/a.out.h weren't very well specified - and didn't work if
           an arch didn't have the asm/ version of that file, but there *was*
           an asm-generic/ version.
           It seems the "ifneq $((wildcard ...),)" for each of those three
           headers in include/kernel/Kbuild is invoked twice during header
           installation, and the second time it matches on the just installed
           asm-generic/kvm_para.h file and thus incorrectly installs
           linux/kvm_para.h as well.
           Most arches actually have an asm/kvm_para.h, so this wasn't
           detectable in those."

      Pull ADM Xen support from Konrad Rzeszutek Wilk:
         * Allow a Linux guest to boot as initial domain and as normal guests
           on Xen on ARM (specifically ARMv7 with virtualized extensions).  PV
           console, block and network frontend/backends are working.
         * Fix compile linux-next fallout.
         * Fix PVHVM bootup crashing.
        The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports
        ARMv7 platforms.
        The goal in implementing this architecture is to exploit the hardware
        as much as possible.  That means use as little as possible of PV
        operations (so no PV MMU) - and use existing PV drivers for I/Os
        (network, block, console, etc).  This is similar to how PVHVM guests
        operate in X86 platform nowadays - except that on ARM there is no need
        for QEMU.  The end result is that we share a lot of the generic Xen
        drivers and infrastructure.
        Details on how to compile/boot/etc are available at this Wiki:

      ACPI: Add new sysfs interface to export device description · d1efe3c3
      Lance Ortiz authored
      Add support to export the device description obtained from the ACPI _STR
      method, if one exists for a device, to user-space via a sysfs interface.
      This new interface provides a standard and platform neutral way for users
      to obtain the description text stored in the ACPI _STR method.  If no
      _STR method exists for the device, no sysfs 'description' file will be
      created.  The 'description' file will be located in the /sys/devices/
      directory using the device's path.
      /sys/device/<bus>/<bridge path>/<device path>.../firmware_node/description
      It can also be located using the ACPI device path, for example:
      Execute the 'cat' command on the 'description' file to obtain the
      description string for that device.
      This patch also includes documentation describing how the new sysfs
      interface works
      Changes from v1-v2 based on comments by Len Brown and Fengguang Wu
      * Removed output "No Description" and leaving a NULL attribute if the
      _STR method failed to evaluate.
      * In acpi_device_remove_files() removed the redundent check of
      dev->pnp.str_obj before calling free.  This check triggered a message
      from smatch.

      Parsing acpi table entries may fall into an infinite loop on a buggy BIOS
      which has entry length=0 in acpi table.
      Instead of kernel hang with few failure clue which leads to heavy lifting debug
      effort, this patch hardens kernel boot by booting into non NUMA mode. The debug
      info left in log buffer helps people identify the issue.
