      cgroup: provide cgroup_nov1= to disable controllers in v1 mounts · 223ffb29
      Johannes Weiner authored
      Testing cgroup2 can be painful with system software automatically
      mounting and populating all cgroup controllers in v1 mode. Sometimes
      they can be unmounted from rc.local, sometimes even that is too late.
      
      Provide a commandline option to disable certain controllers in v1
      mounts, so that they remain available for cgroup2 mounts.
      
      Example use:
      
      cgroup_no_v1=memory,cpu
      cgroup_no_v1=all
      
      Disabling will be confirmed at boot-time as such:
      
      [    0.013770] Disabling cpu control group subsystem in v1 mounts
      [    0.016004] Disabling memory control group subsystem in v1 mounts

      cgroup: make sure a parent css isn't freed before its children · 8bb5ef79
      Tejun Heo authored
      There are three subsystem callbacks in css shutdown path -
      css_offline(), css_released() and css_free().  Except for
      css_released(), cgroup core didn't guarantee the order of invocation.
      css_offline() or css_free() could be called on a parent css before its
      children.  This behavior is unexpected and led to bugs in cpu and
      memory controller.
      
      The previous patch updated ordering for css_offline() which fixes the
      cpu controller issue.  While there currently isn't a known bug caused
      by misordering of css_free() invocations, let's fix it too for
      consistency.
      
      css_free() ordering can be trivially fixed by moving putting of the
      parent css below css_free() invocation.

      children.  This behavior is unexpected and led to bugs in cpu and
      memory controller.
      
      This patch updates offline path so that a parent css is never offlined
      before its children.  Each css keeps online_cnt which reaches zero iff
      itself and all its children are offline and offline_css() is invoked
      only after online_cnt reaches zero.
      
      This fixes the memory controller bug and allows the fix for cpu
      controller.

      cpuset: make mm migration asynchronous · e93ad19d
      Tejun Heo authored
      If "cpuset.memory_migrate" is set, when a process is moved from one
      cpuset to another with a different memory node mask, pages in used by
      the process are migrated to the new set of nodes.  This was performed
      synchronously in the ->attach() callback, which is synchronized
      against process management.  Recently, the synchronization was changed
      from per-process rwsem to global percpu rwsem for simplicity and
      optimization.
      
      Combined with the synchronous mm migration, this led to deadlocks
      because mm migration could schedule a work item which may in turn try
      to create a new worker blocking on the process management lock held
      from cgroup process migration path.
      
      This heavy an operation shouldn't be performed synchronously from that
      deep inside cgroup migration in the first place.  This patch punts the
      actual migration to an ordered workqueue and updates cgroup process
      migration and cpuset config update paths to flush the workqueue after
      all locks are released.  This way, the operations still seem
      synchronous to userland without entangling mm migration with process
      management synchronization.  CPU hotplug can also invoke mm migration
      but there's no reason for it to wait for mm migrations and thus
      doesn't synchronize against their completions.

      Linus Torvalds authored
      Expose an interface to allow users to mark several accesses together as
      being user space accesses, allowing batching of the surrounding user
      space access markers (SMAP on x86, PAN on arm64, domain register
      switching on arm).
      
      This is currently only used for the user string lenth and copying
      functions, where the SMAP overhead on x86 drowned the actual user
      accesses (only noticeable on newer microarchitectures that support SMAP
      in the first place, of course).
      
      * user access batching branch:
        Use the new batched user accesses in generic user string handling
        Add 'unsafe' user access functions for batched accesses

      pwm: Mark all devices as "might sleep" · ff01c944
      Thierry Reding authored
      Commit d1cd2142 ("pwm: Set enable state properly on failed call to
      enable") introduced a mutex that is needed to protect internal state of
      PWM devices. Since that mutex is acquired in pwm_set_polarity() and in
      pwm_enable() and might potentially block, all PWM devices effectively
      become "might sleep".
      
      It's rather pointless to keep the .can_sleep field around, but given
      that there are external users let's postpone the removal for the next
      release cycle.

      Pull more power management and ACPI updates from Rafael Wysocki:
       "This includes fixes on top of the previous batch of PM+ACPI updates
        and some new material as well.
      
        From the new material perspective the most significant are the driver
        core changes that should allow USB devices to stay suspended over
        system suspend/resume cycles if they have been runtime-suspended
        already beforehand.  Apart from that, ACPICA is updated to upstream
        revision 20160108 (cosmetic mostly, but including one fixup on top of
        the previous ACPICA update) and there are some devfreq updates the
        didn't make it before (due to timing).
      
        A few recent regressions are fixed, most importantly in the cpuidle
        menu governor and in the ACPI backlight driver and some x86 platform
        drivers depending on it.
      
        Some more bugs are fixed and cleanups are made on top of that.
      
        Specifics:
      
         - Modify the driver core and the USB subsystem to allow USB devices
           to stay suspended over system suspend/resume cycles if they have
           been runtime-suspended already beforehand and fix some bugs on top
           of these changes (Tomeu Vizoso, Rafael Wysocki).
      
         - Update ACPICA to upstream revision 20160108, including updates of
           the ACPICA's copyright notices, a code fixup resulting from a
           regression fix that was necessary in the upstream code only (the
           regression fixed by it has never been present in Linux) and a
           compiler warning fix (Bob Moore, Lv Zheng).
      
         - Fix a recent regression in the cpuidle menu governor that broke it
           on practically all architectures other than x86 and make a couple
           of optimizations on top of that fix (Rafael Wysocki).
      
         - Clean up the selection of cpuidle governors depending on whether or
           not the kernel is configured for tickless systems (Jean Delvare).
      
         - Revert a recent commit that introduced a regression in the ACPI
           backlight driver, address the problem it attempted to fix in a
           different way and revert one more cosmetic change depending on the
           problematic commit (Hans de Goede).
      
         - Add two more ACPI backlight quirks (Hans de Goede).
      
         - Fix a few minor problems in the core devfreq code, clean it up a
           bit and update the MAINTAINERS information related to it (Chanwoo
           Choi, MyungJoo Ham).
      
         - Improve an error message in the ACPI fan driver (Andy Lutomirski).
      
         - Fix a recent build regression in the cpupower tool (Shreyas
           Prabhu)"

      Pull ARM SoC multiplatform code updates from Arnd Bergmann:
       "This branch is the culmination of 5 years of effort to bring the ARMv6
        and ARMv7 platforms together such that they can all be enabled and
        boot the same kernel.  It has been a tremendous amount of cleanup and
        refactoring by a huge number of people, and creation of several new
        (and major) subsystems to better abstract out all the platform details
        in an appropriate manner.
      
        The bulk of this branch is a large patchset from Arnd that brings
        several of the more minor and older platforms we have closer to
        multiplatform support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0
        and realview Much of this is moving around header files from old mach
        directories, but there are also some cleanup patches of debug_ll
        (lowlevel debug per-platform options) and other parts.
      
        Linus Walleij also has some patchs to clean up the older ARM Realview
        platforms by finally introducing DT support, and Rob Herring has some
        for ARM Versatile which is now DT-only.  Both of these platforms are
        now multiplatform.
      
        Finally, a couple of patches from Russell for Dove PMU, and a fix from
        Valentin Rothberg for Exynos ADC, which were rebased on top of the
        series to avoid conflicts"

      mm: memcontrol: do not uncharge old page in page cache replacement · 44b7a8d3
      Johannes Weiner authored
      Changing page->mem_cgroup of a live page is tricky and fragile.  In
      particular, the memcg writeback code relies on that mapping being stable
      and users of mem_cgroup_replace_page() not overlapping with dirtyable
      inodes.
      
      Page cache replacement doesn't have to do that, though.  Instead of being
      clever and transferring the charge from the old page to the new,
      force-charge the new page and leave the old page alone.  A temporary
      overcharge won't matter in practice, and the old page is going to be freed
      shortly after this anyway.  And this is not performance critical.
