Pull ext4 updates from Ted Ts'o:
 "New features for 3.12:

   - Added aggressive extent caching using the extent status tree.  This
     can actually decrease memory usage in read-mostly workloads since
     the information is much more compactly stored in the extent status
     tree than if we had to keep the extent tree metadata blocks in the
     buffer cache.  This also improves Asynchronous I/O since it is it
     makes much less likely that we need to do metadata I/O to lookup
     the extent tree information.

   - Improve the recovery after corrupted allocation bitmaps are found
     when running in errors=ignore mode.

  Also fixed some writeback vs truncate races when using a blocksize
  less than the page size"

Pull sound updates from Takashi Iwai:
 "Changes are seen in a wide range of codes, mainly due to ASoC DAPM
  requirements; HD-audio shows a high peak in diffstat, it's just a
  removal of bunch of old static quirks.

  Some highlights:

   - HDPM: Updates for AIO/RayDAT support, TCO/sync support

   - RME96: Add PCM sync support

   - HD-audio:

     * A few HDMI/DP audio updates (CA assignment fix, stream switching
       fix, Intel DP device list support)
     * Device specific fixes (ASUS/CXT HP mic support, Thinkpad mic
       improvements, Chromebook fixes, STAC9228 Dell fixes)
     * Replace the all static quirks for AD codecs with the generic
       parser
     * WAKEEN support for handling irqs in the power saving mode

   - USB-audio: Clean up implicit fb handling and related codes

   - DAPM is now mandatory for ASoC CODEC drivers; all existing drivers
     have had some level of DAPM support added.  In addition, a lot of
     cleanups and improvements in DAPM.

   - Support for ASoC cross-platform compile test

   - New drivers and support for Analog Devices ADAU1702 and
     ADAU1401(a), Asahi Kasei Microdevices AK4554, Atmel AT91ASM9x5 and
     WM8904 based machines, Freescale S/PDIF and SSI AC'97, Renesas
     R-Car SoCs, Samsung Exynos5420 SoCs, Texas Instruments PCM1681 and

   - DT bindings for kirkwood and i.MX S/PDIF

   - Clean up and bug fixes: ssm2602, rt5640 and sgtl5000.

Pull pin control changes from Linus Walleij:
 "Here is the bulk of pin control changes for the v3.12 series.  Most of
  the relevant information is in the tag.

  I merged in v3.11-rc7 last week to get rid of a largeish conflict
  within the sunxi (AllWinner) driver in linux-next and fix up the
  non-trivial merge the right way.  That driver had a rather large fix
  adding locking late in the release cycle.

  Overall the bulk changes this time is cleanups and refactorings and
  not much new features, which is nice.

   - Refactorings for generic pin config handling in the core.

   - Factor out a set of device tree utilities for use in all drivers,
     to parse and allocate maps from the device tree.

   - Some fixes to the core such as more nitpicky locking.

   - Pushed down config array iteration into the drivers.

     This patch is necessary for drivers that want to iterate over
     configs and pile up a stack of alterations to the same register(s),
     or if the driver wants to take a local spinlock when committing the
     configuration.

   - A new driver for the Texas Instruments Palmas PMIC by Laxman
     Dewangan.  This is used on the Tegra systems.

   - A major cleanup and modernization of the PFC (Super Hitachi and ARM
     SHmobile) pin controller and subdrivers.

   - Support for the A20 and A31 sunxi (AllWinner) SoCs.

   - A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan
     Carpenter, Julia Lawall and Sachin Kamat did an excellent job here"

        . Honor target pid / tid options when analyzing a file, by David Ahern.

        . Introduce better formatting of syscall arguments, including so
          far beautifiers for mmap, madvise, syscall return values,

          vmlinux has just the initial kernel image, not what is actually
          in use after various code patchings by things like alternatives.
          By Adrian Hunter.

        . Add various improvements and fixes to the "vmlinux matches
          kallsyms" 'perf test' entry, related to the /proc/kcore
          annotation feature. By Adrian Hunter.

        . Add sample parsing test, by Adrian Hunter.

        . Add test for reading object code, by Adrian Hunter.

          scheduler tracepoints that provide the same information as the
          PERF_RECORD_{FORK,EXIT} events. By David Ahern.

        . Remove odd build stall by moving a large struct initialization
          from a local variable to a global one, by Namhyung Kim.

   - 'perf stat' enhancements:

        . Add --initial-delay option to skip measuring for a defined
          startup phase, by Andi Kleen.

   - Generic perf tooling infrastructure/plumbing changes:

        . Tidy up sample parsing validation, by Adrian Hunter.

        . Fix up jobserver setup in libtraceevent Makefile.
          by Arnaldo Carvalho de Melo.

        . Debug improvements, by Adrian Hunter.

        . Fix correlation of samples coming after PERF_RECORD_EXIT event,
          by David Ahern.

        . Improve robustness of the topology parsing code,
          by Stephane Eranian.

        . Add group leader sampling, that allows just one event in a group
          to sample while the other events have just its values read,
          by Jiri Olsa.

        . Add support for a new modifier "D", which requests that the

Pull cgroup updates from Tejun Heo:
 "A lot of activities on the cgroup front.  Most changes aren't visible
  to userland at all at this point and are laying foundation for the
  planned unified hierarchy.

   - The biggest change is decoupling the lifetime management of css
     (cgroup_subsys_state) from that of cgroup's.  Because controllers
     (cpu, memory, block and so on) will need to be dynamically enabled
     and disabled, css which is the association point between a cgroup
     and a controller may come and go dynamically across the lifetime of
     a cgroup.  Till now, css's were created when the associated cgroup
     was created and stayed till the cgroup got destroyed.

     Assumptions around this tight coupling permeated through cgroup
     core and controllers.  These assumptions are gradually removed,
     which consists bulk of patches, and css destruction path is
     completely decoupled from cgroup destruction path.  Note that
     decoupling of creation path is relatively easy on top of these
     changes and the patchset is pending for the next window.

   - cgroup has its own event mechanism cgroup.event_control, which is
     only used by memcg.  It is overly complex trying to achieve high
     flexibility whose benefits seem dubious at best.  Going forward,
     new events will simply generate file modified event and the
     existing mechanism is being made specific to memcg.  This pull
     request contains prepatory patches for such change.

   - Various fixes and cleanups"

While we are likley to succeed and break out of this loop, it isn't
guaranteed.  We should be power and thread friendly if we do have to
go around for a second (or third, or more) attempt.

Pull tty/serial driver patches from Greg KH:
 "Here's the big tty/serial driver pull request for 3.12-rc1.

  Lots of n_tty reworks to resolve some very long-standing issues,
  removing the 3-4 different locks that were taken for every character.
  This code has been beaten on for a long time in linux-next with no
  reported regressions.

  Other than that, a range of serial and tty driver updates and
  revisions.  Full details in the shortlog"

Pull staging tree merge from Greg KH:
 "Here's the bit staging tree pull request for 3.12-rc1.

  Lots of staging driver updates, and fixes.  Lustre is finally enabled
  in the build, and lots of cleanup started happening in it.  There's a
  new wireless driver in here, and 2 new TTY drivers, which cause the
  overall lines added/removed to be quite large on the "added" side.

  The IIO driver updates are also coming through here, as they are tied
  to the staging iio drivers"
