996cd1fb73 cgroup: use do_each_subsys_mask() where applicable
There are several places in cgroup_subtree_control_write() which can
use do_each_subsys_mask() instead of manual mask testing.  Use it.

No functional changes.

b4e0eeafba cgroup: convert for_each_subsys_which() to do-while style
for_each_subsys_which() allows iterating subsystems specified in a
subsystem bitmask; unfortunately, it requires the mask to be an
unsigned long l-value which can be inconvenient and makes it awkward
to use a smaller type for subsystem masks.

This patch converts for_each_subsy_which() to do-while style which
allows it to drop the l-value requirement.  The new iterator is named
do_each_subsys_mask() / while_each_subsys_mask().

5eb385cc5a Revert "cgroup: add cgroup_subsys->css_e_css_changed()"
This reverts commit 56c807ba4e.

cgroup_subsys->css_e_css_changed() was supposed to be used by cgroup
writeback support; however, the change to per-inode cgroup association
made it unnecessary and the callback doesn't have any user.  Remove
it.

223ffb29f9 cgroup: provide cgroup_nov1= to disable controllers in v1 mounts
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

8bb5ef79bc cgroup: make sure a parent css isn't freed before its children
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.

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.

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.

e93ad19d05 cpuset: make mm migration asynchronous
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.

404a47410c Merge branch 'uaccess' (batched user access infrastructure)
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).

  Use the new batched user accesses in generic user string handling

ff01c944cf pwm: Mark all devices as "might sleep"
Commit d1cd214277 ("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.

    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

    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).

Merge tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

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).

03d7d12415 ARM: 64-bit defconfig updates for v4.5
As mentioned earlier, we usually bake this into the general "arm64" branch,
 but this release we have partitioned up the updates a bit more.
 
 Most of these updates are enabling new SoCs in the single defconfig for 64-bit,
 Renesas R8A7795, a number of Tegra options, Socionext Uniphier and a handful
 of new options for other platforms as well.

f9cd69fe5e ARM: SoC defconfig updates for v4.5
As usual, a bunch of commits, mostly adding drivers and other options to
 defconfigs because it makes sense to have them enabled on various development
 or product boards. Too much to enumerate each here.
 
 There's an introduction of a pxa_defconfig, since PXA finally will allow
 building a shared kernel for all boards. With this, we can hopefully
 remove a bunch of individual defconfigs down the road but it requires
 a bit of real life testing and transition period.

6b5a12dbca ARM: SoC multiplatform code changes for v4.5
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.

Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

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"

5083c54264 ARM: SoC cleanups for v4.5
A smallish number of general cleanup commits this release cycle. Some
 of these are minor tweaks:
 
 - shmobile change of binding for their GIC (using arm,pl390 now)
 - ARCH_RENESAS introduction
 - Misc other renesas updates
 
 There's also a couple of treewide commits from Masahiro Yamada cleaning up
 const/__initconst for SMP operation structs and a switch to using "depends
 on" instead of if-constructs on most of the Kconfig platform targets.

19a3dd7621 Do not enable CONFIG_IO_STRICT_DEVMEM by default
Larry Finger reports:
 "My PowerBook G4 Aluminum with a 32-bit PPC processor fails to boot for
  the 4.4-git series".

This is likely due to X still needing /dev/mem access on this platform.

CONFIG_IO_STRICT_DEVMEM is not yet safe to turn on when
CONFIG_STRICT_DEVMEM=y.

Remove the default so that old configurations do not change behavior.

44b7a8d33d mm: memcontrol: do not uncharge old page in page cache replacement
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.

5ccc5abaaf mm: free swap cache aggressively if memcg swap is full
Swap cache pages are freed aggressively if swap is nearly full (>50%
currently), because otherwise we are likely to stop scanning anonymous
when we near the swap limit even if there is plenty of freeable swap cache
pages.  We should follow the same trend in case of memory cgroup, which
has its own swap limit.

3337767850 mm: vmscan: pass memcg to get_scan_count()
memcg will come in handy in get_scan_count().  It can already be used for
getting swappiness immediately in get_scan_count() instead of passing it
around.  The following patches will add more memcg-related values, which
will be used there.

37e8435119 mm: memcontrol: charge swap to cgroup2
This patchset introduces swap accounting to cgroup2.

This patch (of 7):

In the legacy hierarchy we charge memsw, which is dubious, because:

 - memsw.limit must be >= memory.limit, so it is impossible to limit
   swap usage less than memory usage. Taking into account the fact that
   the primary limiting mechanism in the unified hierarchy is
   memory.high while memory.limit is either left unset or set to a very
   large value, moving memsw.limit knob to the unified hierarchy would
   effectively make it impossible to limit swap usage according to the
   user preference.

 - memsw.usage != memory.usage + swap.usage, because a page occupying
   both swap entry and a swap cache page is charged only once to memsw
   counter. As a result, it is possible to effectively eat up to
   memory.limit of memory pages *and* memsw.limit of swap entries, which
   looks unexpected.

That said, we should provide a different swap limiting mechanism for
cgroup2.

This patch adds mem_cgroup->swap counter, which charges the actual number
of swap entries used by a cgroup.  It is only charged in the unified
hierarchy, while the legacy hierarchy memsw logic is left intact.

The swap usage can be monitored using new memory.swap.current file and
limited using memory.swap.max.

Note, to charge swap resource properly in the unified hierarchy, we have
to make swap_entry_free uncharge swap only when ->usage reaches zero, not
just ->count, i.e.  when all references to a swap entry, including the one
taken by swap cache, are gone.  This is necessary, because otherwise
swap-in could result in uncharging swap even if the page is still in swap
cache and hence still occupies a swap entry.  At the same time, this
shouldn't break memsw counter logic, where a page is never charged twice
for using both memory and swap, because in case of legacy hierarchy we
uncharge swap on commit (see mem_cgroup_commit_charge).

0b8f73e104 mm: memcontrol: clean up alloc, online, offline, free functions
The creation and teardown of struct mem_cgroup is fairly messy and
that has attracted mistakes and subtle bugs before.

The main cause for this is that there is no clear model about what
needs to happen when, and that attracts more chaos. So create one:

1. mem_cgroup_alloc() should allocate struct mem_cgroup and its
   auxiliary members and initialize work items, locks etc. so that the
   object it returns is fully initialized and in a neutral state.

2. mem_cgroup_css_alloc() will use mem_cgroup_alloc() to obtain a new
   memcg object and configure it and the system according to the role
   of the new memory-controlled cgroup in the hierarchy.

3. mem_cgroup_css_online() is no longer needed to synchronize with
   iterators, but it verifies css->id which isn't available earlier.

4. mem_cgroup_css_offline() implements stuff that needs to happen upon
   the user-visible destruction of a cgroup, which includes stopping
   all user interfacing as well as releasing certain structures when
   continued memory consumption would be unexpected at that point.

5. mem_cgroup_css_free() prepares the system and the memcg object for
   the object's disappearance, neutralizes its state, and then gives
   it back to mem_cgroup_free().

6. mem_cgroup_free() releases struct mem_cgroup and auxiliary memory.
