      KVM: VMX: mark unusable segment as nonpresent · 03617c18
      Gleb Natapov 提交于
      Some userspaces do not preserve unusable property. Since usable
      segment has to be present according to VMX spec we can use present
      property to amend userspace bug by making unusable segment always
      nonpresent. vmx_segment_access_rights() already marks nonpresent segment
      as unusable.

         ABx500 and TZ1090.  Support BIAS_BUS_HOLD, get device tree parsing
         and debugfs support into shape.
      
       - We also have device tree support with generic naming conventions for
         the generic pin configuration.
      
       - Delete the unused and confusing direct pinconf API.  Now state
         transitions is *the* way to control pins and multiplexing.
      
       - New drivers for Rockchip, TZ1090, and TZ1090 PDC.
      
       - Two pin control states related to power management are now handled in
         the device core: "sleep" and "idle", removing a lot of boilerplate
         code in drivers.  We do not yet know if this is the final word for
         pin PM, but it already make things a lot easier to handle.
      
       - Handle sparse GPIO ranges passing a list of disparate pins, and
         utilize these in the new BayTrail (x86 Atom SoC) driver.
      
       - Make the sunxi (AllWinner) driver handle external interrupts.
      
       - Make it possible for pinctrl-single to handle the case where several
         pins are managed by a single register, and augment it to handle sleep
         modes.
      
       - Cleanups and improvements for the abx500 drivers.
      
       - Move Sirf pin control drivers to their own directory, support
         save/restore of context and add support for the SiRFatlas6 SoC.
      
       - PMU muxing for the Dove pinctrl driver.
      
       - Finalization and support for VF610 in the i.MX6 pinctrl driver.

           hardware designers randomly move things about (mainly when talking

      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 提交于
      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.

      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
           hierarchy support."

      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
        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.
