Pull NFS client updates for Linux 3.4 from Trond Myklebust:
 "New features include:
   - Add NFS client support for containers.

     This should enable most of the necessary functionality, including
     lockd support, and support for rpc.statd, NFSv4 idmapper and
     RPCSEC_GSS upcalls into the correct network namespace from which
     the mount system call was issued.

   - NFSv4 idmapper scalability improvements

     Base the idmapper cache on the keyring interface to allow
     concurrent access to idmapper entries.  Start the process of
     migrating users from the single-threaded daemon-based approach to
     the multi-threaded request-key based approach.

   - NFSv4.1 implementation id.

     Allows the NFSv4.1 client and server to mutually identify each
     other for logging and debugging purposes.

   - Support the 'vers=4.1' mount option for mounting NFSv4.1 instead of
     having to use the more counterintuitive 'vers=4,minorversion=1'.

   - SUNRPC tracepoints.

     Start the process of adding tracepoints in order to improve
     debugging of the RPC layer.

   - pNFS object layout support for autologin.

  Important bugfixes include:

   - Fix a bug in rpc_wake_up/rpc_wake_up_status that caused them to
     fail to wake up all tasks when applied to priority waitqueues.

   - Ensure that we handle read delegations correctly, when we try to
     truncate a file.

   - A number of fixes for NFSv4 state manager loops (mostly to do with
     delegation recovery)."

Pull regmap updates from Mark Brown:
 "Things are really quieting down with the regmap API, while we're still
  seeing a trickle of new features coming in they're getting much
  smaller than they were.  It's also nice to have some features which
  support other subsystems building infrastructure on top of regmap.
  Highlights include:

  - Support for padding between the register and the value when
    interacting with the device, sometimes needed for fast interfaces.
  - Support for applying register updates to the device when restoring
    the register state.  This is intended to be used to apply updates
    supplied by manufacturers for tuning the performance of the device
    (many of which are to undocumented registers which aren't otherwise
    covered).
  - Support for multi-register operations on cached registers.
  - Support for syncing only part of the register cache.
  - Stubs and parameter query functions intended to make it easier for
    other subsystems to build infrastructure on top of the regmap API.

  plus a few driver updates making use of the new features which it was
  easier to merge via this tree."

     management decisions - fixing a weird perf bug.

     There is one thing in the Kconfig that you won't like: "default y

avc_audit() did a lot of jumping around and had a big stack frame, all
for the uncommon case.

Split up the uncommon case (which we really can't make go fast anyway)
into its own slow function, and mark the conditional branches
appropriately for the common likely case.

This causes avc_audit() to no longer show up as one of the hottest
functions on the branch profiles (the new "perf -b" thing), and makes
the cycle profiles look really nice and dense too.

The whole audit path is still annoyingly very much one of the biggest
costs of name lookup, so these things are worth optimizing for.  I wish
we could just tell people to turn it off, but realistically we do need
it: we just need to make sure that the overhead of the necessary evil is
as low as possible.

While doing the fs/namei.c cleanups, I ran sparse on it, and it pointed
out other large integers and a couple of cases of us using '0' instead
of the proper 'NULL'.

Sparse still doesn't understand some of the conditional locking going

Pull nouveau destaging + Kelper modesetting support from Dave Airlie:
 "This pull request is unexpected and not something I had mentioned
  previously.

  So NVIDIA announced new Kepler GPUs this morning, and Ben has killed
  himself getting modesetting support for them together to have on
  launch day.  Most of the code to support the new chips has already
  gone in, however this pull contains a few more pieces along with the
  final enables so the driver binds to the new Kepler cards.  Its quite
  amazing that nouveau can support a GPU on its launch day even if its
  just unaccelerated modesetting, and I'd like to have support in the
  next kernel.

  In order to sweeten the deal, Ben has also requested nouveau destage
  and become ABI stable, the only change is the version number bump
  which he prepared userspace for quite a long time ago.  The driver
  hasn't broken ABI since that one big break that caused a lot of fuss.

  It's also quite a small set of code, and not likely to break anything."

Pull radeon southern islands / trinity support from Dave Airlie:
 "This is support from AMD for their newest GPU and APUs.  The products

  This did come in a bit late, due to some over-complicated AMD internal
  review process, which from the outside seems unnecessary once the
  company has decided it wants to support open source.  However as I
  said previously I'd rather not put the people who've got this hw for 3

Pull drm main changes from Dave Airlie:
 "This is the main drm pull request, I'm probably going to send two more
  smaller ones, will explain below.

  This contains a patch that is also in the fbdev tree, but it should be
  the same patch, it added an API for hot unplugging framebuffer
  devices, and I need that API for a new driver.

  It also contains some changes to the i2c tree which Jean has acked,
  and one change to moorestown platform stuff in x86.

  Highlights:
   - new drivers: UDL driver for USB displaylink devices, kms only,
     should support correct hotplug operations.
   - core: i2c speedups + better hotplug support, EDID overriding via
     firmware interface - allows user to load a firmware for a broken
     monitor/kvm from userspace, it even has documentation for it.
   - exynos: new HDMI audio + hdmi 1.4 + virtual output driver
   - gma500: code cleanup
   - radeon: cleanups, CS optimisations, streamout support and pageflip
     fix
   - nouveau: NVD9 displayport support + more reclocking work
   - i915: re-enabling GMBUS, finish gpu patch (might help hibernation
     who knows), missed irq fixes, stencil tiling fixes, interlaced
     support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB,
     semaphore fixes

  As well as the usual bunch of cleanups and fixes all over the place.

  I've got two things I'd like to merge a bit later:

   a) AMD support for all their new radeonhd 7000 series GPU and APUs.
      AMD dropped this a bit late due to insane internal review
      processes, (please AMD just follow Intel and let open source guys
      ship stuff early) however I don't want to penalise people who own
      this hardware (since its been on sale for 3-4 months and GPU hw
      doesn't exactly have a lifetime in years) and consign them to
      using closed drivers for longer than necessary.  The changes are
      well contained and just plug into the driver new gpu functionality
      so they should be fairly regression proof.  I just want to give
      them a bit of a run on the hw AMD kindly sent me.

   b) drm prime/dma-buf interface code.  This is just infrastructure
      code to expose the dma-buf stuff to drm drivers and to userspace.
      I'm not planning on pushing any driver support in this cycle
      (except maybe exynos), but I'd like to get the infrastructure code
      in so for the next cycle I can start getting the driver support
      into the individual drivers.  We have started driver support for
      i915, nouveau and udl along with I think exynos and omap in
      staging.  However this code relies on the dma-buf tree being
      pulled into your tree first since it needs the latest interfaces
      from that tree.  I'll push to get that tree sent asap.

  (oh and any warnings you see in i915 are gcc's fault from what anyone
  can see)."

Fix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new

On x86, if CONFIG_DEBUG_RODATA is set, one cannot set breakpoints
via KDB.  Apparently this is a well-known problem, as at least one distribution
now ships with both KDB enabled and CONFIG_DEBUG_RODATA=y for security reasons.

This patch adds an printk message to the breakpoint failure case,
in order to provide suggestions about how to use the debugger.

This fixes a bug with setting a breakpoint during kdb initialization
(from kdb_cmds).  Any call to kdb_printf() before the initialization
of the kgdboc serial console driver (which happens much later during
bootup than kdb_init), results in kernel panic due to the use of
dbg_io_ops before it is initialized.

Sometimes it is desirable to stop the kernel debugger before allowing
a system to reboot either with kdb or kgdb.  This patch adds the
ability to turn the reboot notifier on and off or enter the debugger
and stop kernel execution before rebooting.

It is possible to change the setting after booting the kernel with the
following:

echo 1 > /sys/module/debug_core/parameters/kgdbreboot

It is also possible to change this setting using kdb / kgdb to
manipulate the variable directly.

Using KDB:
   mm kgdbreboot 1

Using gdb:
   set kgdbreboot=1

This fixes the following problems:
1) Typematic-repeat of 'enter' gives warning message
   and leaks make/break if KDB exits. Repeats
   look something like 0x1c 0x1c .... 0x9c
2) Use of 'keypad enter' gives warning message and
   leaks the ENTER break/make code out if KDB exits.
   KP ENTER repeats look someting like 0xe0 0x1c
   0xe0 0x1c ... 0xe0 0x9c.
3) Lag on the order of seconds between "break" and "make" when
   expecting the enter "break" code. Seen under virtualized
   environments such as VMware ESX.

The existing special enter handler tries to glob the enter break code,
but this fails if the other (KP) enter was used, or if there was a key
repeat. It also fails if you mashed some keys along with enter, and
you ended up with a non-enter make or non-enter break code coming
after the enter make code. So first, we modify the handler to handle
these cases. But performing these actions on every enter is annoying
since now you can't hold ENTER down to scroll <more>d messages in
KDB. Since this special behaviour is only necessary to handle the
exiting KDB ('g' + ENTER) without leaking scancodes to the OS.  This
cleanup needs to get executed anytime the kdb_main loop exits.

Tested on QEMU. Set a bp on atkbd.c to verify no scan code was leaked.

Pull updates of sound stuff from Takashi Iwai:
 "Here is the first big update chunk of sound stuff for 3.4-rc1.

  In the common sound infrastructure, there are a few changes for
  dynamic PCM support (used in ASoC) and a few clean-ups.  Majority of
  changes are found, as usual, in HD-audio and ASoC.

  Some highlights of HD-audio changes:

   - All the long-standing static quirk codes for Realtek codec were
     finally removed by fixing and extending the Realtek auto-parser.

   - The mute-LED control is standardized over all HD-audio codec
     drivers using the extended vmaster hook.

   - The vmaster slave mixer elements are initialized to 0dB as default
     so that the user won't be annoyed by the silent output after
     updates, e.g.  due to the additions of new elements.

   - Other many fix-ups for the misc HD-audio devices.

  In the ASoC side, this is a very active release, including a quite a
  few framework enhancements.  Some highlights:

   - Support for widgets not associated with a CODEC, an important part
     of the dynamic PCM framework.

   - A library factoring out the common code shared by dmaengine based
     DMA drivers contributed by Lars-Peter Clausen.  This will save a
     lot of code and make it much easier to deploy enhancements to
     dmaengine.

   - Support for binary controls, used for providing runtime
     configuration of algorithm coefficients.

   - A new DAPM widget type for regulator supplies allowing drivers for
     devices that can power down unused supplies while active to do
     without any per-driver code.

   - DAPM widgets for DAIs, initially giving a speed boost for playback
     startup and shutdown and also the basis for CODEC<->CODEC DAI link
     support.

   - Support for specifying the number of significant bits on audio
     interfaces, useful for allowing applications to know how much
     effort to put into generating data for a larger sample format.

   - Conversion of the FSI driver used on some SH processors to
     DMAEngine.

   - Conversion of EP93xx drivers to DMAEngine.

   - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
     WM2200.

   - Move audmux driver from arc/arm to sound/soc

   - McBSP move from arch/ to sound/ and updates

  Also, a few small updates and fixes for other drivers like au88x0,
  ymfpci, USB 6fire, USB usx2yaudio are included."
