      Pull regmap updates from Mark Brown:
       "A small but useful set of regmap updates this time around:
      
         - An abstraction for bitfields within a register map contributed by
           Srinivas Kandagatla, allowing drivers to cope more easily when
           hardware designers randomly move things about (mainly when talking
           to things like system controllers).
      
         - Changes from Lars-Peter Clausen to allow the MMIO regmap to be used
           from hard IRQ context.
      
         - Small improvements to the cache infrastructure and performance,
           including a default cache sync operation so now all regmaps can
           sync easily.
      
        There's also a pinctrl driver making use of the new bitfield API,
        merged here for dependency reasons.  There will be a simple add/add
        conflict with the pinctrl tree as a result."

       "Here is a batch of GPIO changes for v3.11.  I have agreed with Grant
        to take care of the pull requests for this development cycle.
      
        No special things are happening in the GPIO tree this time (nice with
        some calm) and I have been extra careful to do regression builds and
        it's well boiled in -next.
      
        GPIO changes for the v3.11 development cycle:
         - Incremental development for the Langwell (Atom SoC), Xilinx, ICH
           and RCAR drivers.

      Pull first batch of ARC changes from Vineet Gupta:
       "There's a second bunch to follow next week - which depends on commits
        on other trees (irq/net).  I'd have preferred the accompanying ARC
        change via respective trees, but it didn't workout somehow.
      
        Highlights of changes:
      
         - Continuation of ARC MM changes from 3.10 including
      
             zero page optimization
             Setting pagecache pages dirty by default
             Non executable stack by default
             Reducing dcache flushes for aliasing VIPT config
      
         - Long overdue rework of pt_regs machinery - removing the unused word
           gutters and adding ECR register to baseline (helps cleanup lot of
           low level code)
      
         - Support for ARC gcc 4.8
      
         - Few other preventive fixes, cosmetics, usage of Kconfig helper..

        header split as well as beautification of macros in entry.h"

      Pull ARM updates from Russell King:
       "This contains the usual updates from other people (listed below) and
        the usual random muddle of miscellaneous ARM updates which cover some
        low priority bug fixes and performance improvements.
      
        I've started to put the pull request wording into the merge commits,
        which are:
      
         - NoMMU stuff:
      
           This includes the following series sent earlier to the list:
            - nommu-fixes
            - R7 Support
            - MPU support
      
           I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
           were discussing today until we've reached a conclusion/that's had
           some more review.
      
           This is rebased (and re-tested) on your devel-stable branch because
           otherwise there were going to be conflicts with Uwe's V7M work now
           that you've merged that.  I've included the fix for limiting MPU to
           CPU_V7.
      
         - Huge page support
      
           These changes bring both HugeTLB support and Transparent HugePage
           (THP) support to ARM.  Only long descriptors (LPAE) are supported
           in this series.
      
           The code has been tested on an Arndale board (Exynos 5250).
      
         - LPAE updates
      
           Please pull these miscellaneous LPAE fixes I've been collecting for
           a while now for 3.11.  They've been tested and reviewed by quite a
           few people, and most of the patches are pretty trivial.  -- Will Deacon.
      
         - arch_timer cleanups
      
           Please pull these arch_timer cleanups I've been holding onto for a
           while.  They're the same as my last posting, but have been rebased
           to v3.10-rc3.
      
         - mpidr linearisation (multiprocessor id register - identifies which
           CPU number we are in the system)
      
           This patch series that implements MPIDR linearization through a
           simple hashing algorithm and updates current cpu_{suspend}/{resume}
           code to use the newly created hash structures to retrieve context
           pointers.  It represents a stepping stone for the implementation of
           power management code on forthcoming multi-cluster ARM systems.
      
           It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
           OMAP4 and Tegra, with processors hitting low-power states requiring
           warm-boot resume through the cpu_resume code path"

      For those file systems(btrfs/ext4/ocfs2/tmpfs) that support
      SEEK_DATA/SEEK_HOLE functions, we end up handling the similar
      matter in lseek_execute() to update the current file offset
      to the desired offset if it is valid, ceph also does the
      simliar things at ceph_llseek().
      
      To reduce the duplications, this patch make lseek_execute()
      public accessible so that we can call it directly from the
      underlying file systems.
      
      Thanks Dave Chinner for this suggestion.
      
      [AV: call it vfs_setpos(), don't bring the removed 'inode' argument back]
      
      v2->v1:
      - Add kernel-doc comments for lseek_execute()
      - Call lseek_execute() in ceph->llseek()

       "This pull request contains the following changes.
      
         - cgroup_subsys_state (css) reference counting has been converted to
           percpu-ref.  css is what each resource controller embeds into its
           own control structure and perform reference count against.  It may
           be used in hot paths of various subsystems and is similar to module
           refcnt in that aspect.  For example, block-cgroup's css refcnting
           was showing up a lot in Mikulaus's device-mapper scalability work
           and this should alleviate it.
      
         - cgroup subtree iterator has been updated so that RCU read lock can
           be released after grabbing reference.  This allows simplifying its
           users which requires blocking which used to build iteration list
           under RCU read lock and then traverse it outside.  This pull
           request contains simplification of cgroup core and device-cgroup.
           A separate pull request will update cpuset.
      
         - Fixes for various bugs including corner race conditions and RCU
           usage bugs.

      Pull workqueue changes from Tejun Heo:
       "Surprisingly, Lai and I didn't break too many things implementing
        custom pools and stuff last time around and there aren't any follow-up
        changes necessary at this point.
      
        The only change in this pull request is Viresh's patches to make some
        per-cpu workqueues to behave as unbound workqueues dependent on a boot
        param whose default can be configured via a config option.  This leads
        to higher processing overhead / lower bandwidth as more work items are
        bounced across CPUs; however, it can lead to noticeable powersave in
        certain configurations - ~10% w/ idlish constant workload on a
        big.LITTLE configuration according to Viresh.
      
        This is because per-cpu workqueues interfere with how the scheduler
        perceives whether or not each CPU is idle by forcing pinned tasks on
        them, which makes the scheduler's power-aware scheduling decisions
        less effective.
      
        Its effectiveness is likely less pronounced on homogenous
        configurations and this type of optimization can probably be made
        automatic; however, the changes are pretty minimal and the affected
        workqueues are clearly marked, so it's an easy gain for some
        configurations for the time being with pretty unintrusive changes."

        The usual usage is relatively straight-forward although async kill

        There also are some interface concerns - e.g.  I'm not sure about

      Pull voluntary preemption fixes from Ingo Molnar:
       "This tree contains a speedup which is achieved through better
        might_sleep()/might_fault() preemption point annotations for uaccess
        functions, by Michael S Tsirkin:
      
        1. The only reason uaccess routines might sleep is if they fault.
           Make this explicit for all architectures.
      
        2. A voluntary preemption point in uaccess functions means compiler
           can't inline them efficiently, this breaks assumptions that they
           are very fast and small that e.g.  net code seems to make.  Remove
           this preemption point so behaviour matches with what callers
           assume.
      
        3. Accesses (e.g through socket ops) to kernel memory with KERNEL_DS
           like net/sunrpc does will never sleep.  Remove an unconditinal
           might_sleep() in the might_fault() inline in kernel.h (used when
           PROVE_LOCKING is not set).
      
        4. Accesses with pagefault_disable() return EFAULT but won't cause
           caller to sleep.  Check for that and thus avoid might_sleep() when
           PROVE_LOCKING is set.
      
        These changes offer a nice speedup for CONFIG_PREEMPT_VOLUNTARY=y
        kernels, here's a network bandwidth measurement between a virtual
        machine and the host:

        used here is called wait/wound in the RDBMS literature: The older
