Merge mmu_notifier fixes from Jérôme Glisse:
 "The invalidate_page callback suffered from 2 pitfalls. First it used
  to happen after page table lock was release and thus a new page might
  have been setup for the virtual address before the call to
  invalidate_page().

  This is in a weird way fixed by commit c7ab0d2f ("mm: convert
  try_to_unmap_one() to use page_vma_mapped_walk()") which moved the
  callback under the page table lock. Which also broke several existing
  user of the mmu_notifier API that assumed they could sleep inside this
  callback.

  The second pitfall was invalidate_page being the only callback not
  taking a range of address in respect to invalidation but was giving an
  address and a page. Lot of the callback implementer assumed this could
  never be THP and thus failed to invalidate the appropriate range for
  THP pages.

  By killing this callback we unify the mmu_notifier callback API to
  always take a virtual address range as input.

  There is now two clear API (I am not mentioning the youngess API which
  is seldomly used):

   - invalidate_range_start()/end() callback (which allow you to sleep)

   - invalidate_range() where you can not sleep but happen right after
     page table update under page table lock

  Note that a lot of existing user feels broken in respect to
  range_start/ range_end. Many user only have range_start() callback but
  there is nothing preventing them to undo what was invalidated in their
  range_start() callback after it returns but before any CPU page table
  update take place.

  The code pattern use in kvm or umem odp is an example on how to
  properly avoid such race. In a nutshell use some kind of sequence
  number and active range invalidation counter to block anything that
  might undo what the range_start() callback did.

  If you do not care about keeping fully in sync with CPU page table (ie
  you can live with CPU page table pointing to new different page for a
  given virtual address) then you can take a reference on the pages
  inside the range_start callback and drop it in range_end or when your
  driver is done with those pages.

  Last alternative is to use invalidate_range() if you can do
  invalidation without sleeping as invalidate_range() callback happens
  under the CPU page table spinlock right after the page table is
  updated.

  The first two patches convert existing mmu_notifier_invalidate_page()
  calls to mmu_notifier_invalidate_range() and bracket those call with
  call to mmu_notifier_invalidate_range_start()/end().

  The next ten patches remove existing invalidate_page() callback as it
  can no longer happen.

  Finally the last page remove the invalidate_page() callback completely
  so it can RIP.

  Changes since v1:
   - remove more dead code in kvm (no testing impact)
   - more accurate end address computation (patch 2) in page_mkclean_one
     and try_to_unmap_one
   - added tested-by/reviewed-by gotten so far"

jfs had previously avoided the use of MAX_LFS_FILESIZE because it hadn't
accounted for the whole 32-bit index range on 32-bit systems.  That has
been fixed by commit 0cc3b0ec ("Clarify (and fix) MAX_LFS_FILESIZE

dtc uses an incorrect format specifier for printing a uint64_t value.
uint64_t may be either 'unsigned long' or 'unsigned long long' depending
on the host architecture.

Fix this by using %llx and casting to unsigned long long, which ensures
that we always have a wide enough variable to print 64 bits of hex.

Commit c7acec71 ("kernel.h: handle pointers to arrays better in
container_of()") made use of __compiletime_assert() from container_of()
thus increasing the usage of this macro, allowing developers to notice
type conflicts in usage of container_of() at compile time.

However, the implementation of __compiletime_assert relies on compiler
optimizations to report an error.  This means that if a developer uses
"-O0" with any code that performs container_of(), the compiler will always
report an error regardless of whether there is an actual problem in the
code.

This patch disables compile_time_assert when optimizations are disabled to
allow such code to compile with CFLAGS="-O0".

Example compilation failure:

./include/linux/compiler.h:547:38: error: call to `__compiletime_assert_94' declared with attribute error: pointer type mismatch in container_of()

Wendy Wang reported off-list that a RAS HWPOISON-SOFT test case failed
and bisected it to the commit 479f854a ("mm, page_alloc: defer
debugging checks of pages allocated from the PCP").

The problem is that a page that was poisoned with madvise() is reused.
The commit removed a check that would trigger if DEBUG_VM was enabled
but re-enabling the check only fixes the problem as a side-effect by
printing a bad_page warning and recovering.

The root of the problem is that an madvise() can leave a poisoned page
on the per-cpu list.  This patch drains all per-cpu lists after pages
are poisoned so that they will not be reused.  Wendy reports that the
test case in question passes with this patch applied.  While this could
be done in a targeted fashion, it is over-complicated for such a rare
operation.

Commit 7c051267 ("mm, fork: make dup_mmap wait for mmap_sem for
write killable") made it possible to kill a forking task while it is
waiting to acquire its ->mmap_sem for write, in dup_mmap().

However, it was overlooked that this introduced an new error path before
the new mm_struct's ->uprobes_state.xol_area has been set to NULL after
being copied from the old mm_struct by the memcpy in dup_mm().  For a
task that has previously hit a uprobe tracepoint, this resulted in the
'struct xol_area' being freed multiple times if the task was killed at
just the right time while forking.

Fix it by setting ->uprobes_state.xol_area to NULL in mm_init() rather
than in uprobe_dup_mmap().

With CONFIG_UPROBE_EVENTS=y, the bug can be reproduced by the same C
program given by commit 2b7e8665 ("fork: fix incorrect fput of
->exe_file causing use-after-free"), provided that a uprobe tracepoint
has been set on the fork_thread() function.  For example:

    $ gcc reproducer.c -o reproducer -lpthread
    $ nm reproducer | grep fork_thread
    0000000000400719 t fork_thread
    $ echo "p $PWD/reproducer:0x719" > /sys/kernel/debug/tracing/uprobe_events
    $ echo 1 > /sys/kernel/debug/tracing/events/uprobes/enable

We are doing a last second memory allocation attempt before calling
out_of_memory().  But since slab shrinker functions might indirectly
wait for other thread's __GFP_DIRECT_RECLAIM && !__GFP_NORETRY memory
allocations via sleeping locks, calling slab shrinker functions from
node_reclaim() from get_page_from_freelist() with oom_lock held has
possibility of deadlock.  Therefore, make sure that last second memory
allocation attempt does not call slab shrinker functions.

Replace all mmu_notifier_invalidate_page() calls by *_invalidate_range()
and make sure it is bracketed by calls to *_invalidate_range_start()/end().

Note that because we can not presume the pmd value or pte value we have
to assume the worst and unconditionaly report an invalidation as
happening.

Changed since v2:
  - try_to_unmap_one() only one call to mmu_notifier_invalidate_range()
  - compute end with PAGE_SIZE << compound_order(page)
  - fix PageHuge() case in try_to_unmap_one()

The PowerA gamepad initialization quirk worked with the PowerA
wired gamepad I had around (0x24c6:0x543a), but a user reported [0]
that it didn't work for him, even though our gamepads shared the
same vendor and product IDs.

When I initially implemented the PowerA quirk, I wanted to avoid
actually triggering the rumble action during init. My tests showed
that my gamepad would work correctly even if it received a rumble
of 0 intensity, so that's what I went with.

Unfortunately, this apparently isn't true for all models (perhaps
a firmware difference?). This non-working gamepad seems to require
the real magic rumble packet that the Microsoft driver sends, which
actually vibrates the gamepad. To counteract this effect, I still
send the old zero-rumble PowerA quirk packet which cancels the
rumble effect before the motors can spin up enough to vibrate.

ASoC: Fixes for v4.13

A couple of fixes, one for a regression in simple-card introduced during
the merge window that was only reported this week and another for a
regression in registration of ACPI GPIOs.

Merge tag 'vfio-ccw-20170724' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/vfio-ccw into fixes

Pull vfio-ccw fix from Cornelia Huck:
"A bugfix in the ccw translation code."

A 31-bit compat process can force a BUG_ON in crst_table_upgrade
with specific, invalid mmap calls, e.g.

   mmap((void*) 0x7fff8000, 0x10000, 3, 32, -1, 0)

The arch_get_unmapped_area[_topdown] functions miss an if condition
in the decision to do a page table upgrade.

The mm->context.asce field of a new process is not set up correctly
in case of a fork with a 5 level page table.
Add the missing case to init_new_context().

Pull libnvdimm fix from Dan Williams:
 "A single patch removing some structure definitions from a uapi header
  file. These payloads are never processed directly by the kernel they
  are simply passed through an ioctl as opaque blobs to the ACPI _DSM
  (Device Specific Method) interface.

  Userspace should not be depending on the kernel to define these
  payloads. We will instead provide these definitions via the existing
  libndctl (https://github.com/pmem/ndctl) project that has NVDIMM
  command helpers and other definitions"
