      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"

      vfs: export lseek_execute() to modules · 46a1c2c7
      Jie Liu authored
      
      
      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()

      Pull cpuset changes from Tejun Heo:
       "cpuset has always been rather odd about its configurations - a cgroup
        right after creation didn't allow any task executions before
        configuration, changing configuration in the parent modifies the
        descendants irreversibly and so on.  These behaviors are inherently
        nasty and almost hostile against sharing the hierarchy with other
        controllers making it very difficult to use in unified hierarchy.
      
        Li is currently in the process of updating the behaviors for
        __DEVEL__sane_behavior which is the bulk of changes in this pull
        request.  It isn't complete yet and the behaviors will change further
        but all changes are gated behind sane_behavior.  In the process, the
        rather hairy work-item punting which was used to work around the
        limitations of cgroup descendant iterator was simplified."

      Pull cgroup changes from Tejun Heo:
       "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.
      
         - A lot of cleanups and some prepartory work for the planned unified

      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."

       "This pull request contains Kent's per-cpu reference counter.  It has

        The usual usage is relatively straight-forward although async kill
        confirm interface, which is not used int most cases, is somewhat icky.
        There also are some interface concerns - e.g.  I'm not sure about
        passing in @relesae callback during init as that becomes funny when we
        later implement synchronous kill_and_drain - but nothing too serious
        and it's quite useable now.

      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:

        Wound/wait mutexes are used when other multiple lock acquisitions of a

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

        tasks needs to back off and drop all the locks it is currently
        holding, ie the younger task is wounded.

        As we proceed to untangle the dependencies between platform code and
        driver code, the amount of changes in this category is fortunately
        shrinking, for 3.11 we have 16 branches here and 101 non-merge
        changesets, the majority of which are for the stedma40 dma engine
        driver used in the ux500 platform.  Cleaning up that code touches
        multiple subsystems, but gets rid of the dependency in the end.
      
        The mailbox code moved out from mach-omap2 to drivers/mailbox is an
        intermediate step and is still omap specific at the moment.  Patches
        exist to generalize the subsystem and add other drivers with the same

      Pull ARM SoC specific changes from Arnd Bergmann:
       "These changes are all to SoC-specific code, a total of 33 branches on
        17 platforms were pulled into this.  Like last time, Renesas sh-mobile
        is now the platform with the most changes, followed by OMAP and
        EXYNOS.
      
        Two new platforms, TI Keystone and Rockchips RK3xxx are added in this
        branch, both containing almost no platform specific code at all, since
        they are using generic subsystem interfaces for clocks, pinctrl,
        interrupts etc.  The device drivers are getting merged through the
        respective subsystem maintainer trees.
      
        One more SoC (u300) is now multiplatform capable and several others
        (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
        towards that goal with this series but need more work.
      
        Also noteworthy is the work on PCI here, which is traditionally part
        of the SoC specific code.  With the changes done by Thomas Petazzoni,
        we can now more easily have PCI host controller drivers as loadable
        modules and keep them separate from the platform code in
        drivers/pci/host.  This has already led to the discovery that three
        platforms (exynos, spear and imx) are actually using an identical PCIe
        host controller and will be able to share a driver once support for
        spear and imx is added."

      Pull ARM SoC non-cricitical bug fixes from Arnd Bergmann:
       "These are various bug fixes that were not considered important enough
        for merging into 3.10.
      
        The majority of the ARM fixes are for the OMAP and at91 platforms, and
        there is another set of bug fixes for device drivers that resolve
        'randconfig' build errors and that the subsystem maintainers either
        did not pick up or preferred to get merged through the arm-soc tree."

        Lots of little things, and larger firmware subsystem updates, all

        of CONFIG_HOTPLUG, after 10+ years, thanks to Stephen Rohtwell (it had
        been always on for a number of kernel releases, now it's just
        removed)"
