      Pull ext2, ext3 and quota fixes from Jan Kara:
       "Interesting bits are:
         - removal of a special i_mutex locking subclass (I_MUTEX_QUOTA) since
           quota code does not need i_mutex anymore in any unusual way.
         - backport (from ext4) of a fix of a checkpointing bug (missing cache
           flush) that could lead to fs corruption on power failure
      
        The rest are just random small fixes & cleanups."

      Pull KVM changes from Avi Kivity:
       "Changes include additional instruction emulation, page-crossing MMIO,
        faster dirty logging, preventing the watchdog from killing a stopped
        guest, module autoload, a new MSI ABI, and some minor optimizations
        and fixes.  Outside x86 we have a small s390 and a very large ppc
        update.
      
        Regarding the new (for kvm) rebaseless workflow, some of the patches
        that were merged before we switch trees had to be rebased, while
        others are true pulls.  In either case the signoffs should be correct
        now."

       "This has the generic strncpy_from_user() implementation architectures
        can now use, which we've been developing on linux-arch over the past
        few days.
      
        For good measure I ran both a 32-bit and a 64-bit glibc testsuite run,
        and the latter of which pointed out an adjustment I needed to make to
        sparc's user_addr_max() definition.  Linus, you were right, STACK_TOP
        was not the right thing to use, even on sparc itself :-)
      
        From Sam Ravnborg, we have a conversion of sparc32 over to the common
        alloc_thread_info_node(), since the aspect which originally blocked
        our doing so (sun4c) has been removed."

      Pull more relocation fixes from Peter Anvin:
       "These are additional symbols that have been found to either be
        absolute or look like they might end up being absolute on one version
        of GNU ld or another.  Unfortunately we have since that a different
        GNU ld version, 2.21, can generate bogus absolute symbols; again, this
        would have caused a malfunctioning kernel on x86-32 if relocated.
      
        The relocs.c changes changed silent corruption to a build time error.
      
        It is worth noting that if the various barrier symbols we use were
        more consistent in the namespace used this probably could be reduced
        to a single regexp; if nothing else it looks like there is migration
        toward a common __(start|stop)___.* namespace."

      sparc: Fix user_addr_max() definition. · c5389831
      David S. Miller authored
      
      
      We need to use TASK_SIZE because for 64-bit tasks the value
      of STACK_TOP actually sits in the middle of the address space
      so we'll get false-negatives.
      
      Adjust the TASK_SIZE definition on sparc64 to accomodate this,
      in the context in which user_addr_max() is used we have the
      test_thread_flag() definition available but not the one for
      test_tsk_thread_flag().

      lib: Sparc's strncpy_from_user is generic enough, move under lib/ · 2922585b
      David S. Miller authored
      
      
      To use this, an architecture simply needs to:
      
      1) Provide a user_addr_max() implementation via asm/uaccess.h
      
      2) Add "select GENERIC_STRNCPY_FROM_USER" to their arch Kcnfig
      
      3) Remove the existing strncpy_from_user() implementation and symbol
         exports their architecture had.

       "This is the main merge window request for the drm.
      
        It's big, but jam packed will lots of features and of course 0
        regressions.  (okay maybe there'll be one).
      
        Highlights:
      
         - new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
           (qemu only).  These drivers use the generic modesetting drivers.
      
         - initial prime/dma-buf support for i915, nouveau, radeon, udl and
           exynos
      
         - switcheroo audio support: so GPUs with HDMI can turn off the sound
           driver without crashing stuff.
      
         - There are some patches drifting outside drivers/gpu into x86 and
           EFI for better handling of multiple video adapters in Apple Macs,
           they've got correct acks except one trivial fixup.
      
         - Core:
      	edid parser has better DMT and reduced blanking support,
      	crtc properties,
      	plane properties,
      
         - Drivers:
      	exynos: add 2D core accel support, prime support, hdmi features
      	intel: more Haswell support, initial Valleyview support, more
      	    hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
      	    cleanups and fixes
      	radeon: more HDMI audio support, improved GPU lockup recovery
      	    support, remove nested mutexes, less memory copying on PCIE, fix
      	    bus master enable race (kexec), improved fence handling
      	gma500: cleanups, 1080p support, acpi fixes
      	nouveau: better nva3 memory reclocking, kepler accel (needs
      	    external firmware rip), async buffer moves on nv84+ hw.
      
        I've some more dma-buf patches that rely on the dma-buf merge for vmap
        stuff, and I've a few fixes building up, but I'd decided I'd better
        get rid of the main pull sooner rather than later, so the audio guys
        are also unblocked."

      Linus Torvalds authored
      Pull user-space probe instrumentation from Ingo Molnar:
       "The uprobes code originates from SystemTap and has been used for years
        in Fedora and RHEL kernels.  This version is much rewritten, reviews
        from PeterZ, Oleg and myself shaped the end result.
      
        This tree includes uprobes support in 'perf probe' - but SystemTap
        (and other tools) can take advantage of user probe points as well.
      
        Sample usage of uprobes via perf, for example to profile malloc()
        calls without modifying user-space binaries.
      
        First boot a new kernel with CONFIG_UPROBE_EVENT=y enabled.
      
        If you don't know which function you want to probe you can pick one
        from 'perf top' or can get a list all functions that can be probed
        within libc (binaries can be specified as well):
      
      	$ perf probe -F -x /lib/libc.so.6
      
        To probe libc's malloc():
      
      	$ perf probe -x /lib64/libc.so.6 malloc
      	Added new event:
      	probe_libc:malloc    (on 0x7eac0)
      
        You can now use it in all perf tools, such as:
      
      	perf record -e probe_libc:malloc -aR sleep 1
      
        Make use of it to create a call graph (as the flat profile is going to
        look very boring):
      
      	$ perf record -e probe_libc:malloc -gR make
      	[ perf record: Woken up 173 times to write data ]
      	[ perf record: Captured and wrote 44.190 MB perf.data (~1930712

        The core uprobes design is fairly straightforward: uprobes probe
        points register themselves at (inode:offset) addresses of
        libraries/binaries, after which all existing (or new) vmas that map
        that address will have a software breakpoint injected at that address.
        vmas are COW-ed to preserve original content.  The probe points are
        kept in an rbtree.
      
        If user-space executes the probed inode:offset instruction address
        then an event is generated which can be recovered from the regular
        perf event channels and mmap-ed ring-buffer.
      
        Multiple probes at the same address are supported, they create a
        dynamic callback list of event consumers.
      
        The basic model is further complicated by the XOL speedup: the
        original instruction that is probed is copied (in an architecture
        specific fashion) and executed out of line when the probe triggers.
        The XOL area is a single vma per process, with a fixed number of
        entries (which limits probe execution parallelism).
      
        The API: uprobes are installed/removed via
        /sys/kernel/debug/tracing/uprobe_events, the API is integrated to
        align with the kprobes interface as much as possible, but is separate
        to it.
      
        Injecting a probe point is privileged operation, which can be relaxed
        by setting perf_paranoid to -1.
      
        You can use multiple probes as well and mix them with kprobes and
        regular PMU events or tracepoints, when instrumenting a task."
      
      Fix up trivial conflicts in mm/memory.c due to previous cleanup of
      unmap_single_vma().

      Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input · 2c01e7bc
      Linus Torvalds authored
      Pull input layer updates from Dmitry Torokhov:
       - a bunch of new drivers (DA9052/53 touchscreenn controller, Synaptics
         Navpoint, LM8333 keypads, Wacom I2C touhscreen);
       - updates to existing touchpad drivers (ALPS, Sntelic);
       - Wacom driver now supports Intuos5;
       - device-tree bindings in numerous drivers;
       - other cleanups and fixes.
      
      Fix annoying conflict in drivers/input/tablet/wacom_wac.c that I think
      implies that the input layer device naming is broken, but let's see.  I
      brough it up with Dmitry.

      x86, relocs: Add jiffies and jiffies_64 to the relative whitelist · ea17e741
      H. Peter Anvin authored
      The symbol jiffies is created in the linker script as an alias to
      jiffies_64.  Unfortunately this is done outside any section, and
      apparently GNU ld 2.21 doesn't carry the section with it, so we end up
      with an absolute symbol and therefore a broken kernel.
      
      Add jiffies and jiffies_64 to the whitelist.
      
      The most disturbing bit with this discovery is that it shows that we
      have had multiple linker bugs in this area crossing multiple
      generations, and have been silently building bad kernels for some time.

      Dmitry Torokhov authored
      
      
      Keymaps used by drivers based on matrix-keymap facilities are arrays of
      unsigned shorts, not chars. Treating them otherwise produces corrupted
      keymaps.

      drm/nouveau: Unregister switcheroo client on exit · 5c5ed6e2

      Currently nouveau only registers as a vga_switcheroo client, but never
      unregisters. This patch adds the necessary unregister calls.

      drm/nouveau: Check dsm on switcheroo unregister · 2f3787aa
      Andreas Heider authored
      
      
      Currently vga_switcheroo_unregister_handler is called unconditionally when
      nouveau is unloaded, even when nouveau never registered a handler. This
      interferes with other switcheroo handlers, as vga_switcheroo doesn't check who
      called unregister_handler, but simply unregisters the current handler. This
      patch adds a check so unregister is only called if a handler was registered by
      nouveau before.
