Subject: [GIT PULL] arm64 2nd set of updates for 4.12

Hi Linus,

Please pull the arm64 updates below. The mm/vmalloc.c change was acked
by Michal Hocko and the arch/arm one by Russell King. Thanks.

The following changes since commit 92f66f84d9695d07adf9bc987bbcce4bf9b8e87c:

  arm64: Fix the DMA mmap and get_sgtable API with DMA_ATTR_FORCE_CONTIGUOUS (2017-05-05 11:41:35 +0100)

  arm64: Silence first allocation with CONFIG_ARM64_MODULE_PLTS=y (2017-05-11 14:43:40 +0100)

----------------------------------------------------------------
arm64 2nd set of updates for 4.12:

- Silence module allocation failures when CONFIG_ARM*_MODULE_PLTS is
  enabled. This requires a check for __GFP_NOWARN in alloc_vmap_area()

- Improve/sanitise user tagged pointers handling in the kernel

- Inline asm fixes/cleanups

----------------------------------------------------------------
Florian Fainelli (3):
      mm: Silence vmap() allocation failures based on caller gfp_flags
      ARM: Silence first allocation with CONFIG_ARM_MODULE_PLTS=y
      arm64: Silence first allocation with CONFIG_ARM64_MODULE_PLTS=y

Kristina Martsenko (4):
      arm64: traps: fix userspace cache maintenance emulation on a tagged pointer
      arm64: hw_breakpoint: fix watchpoint matching for tagged pointers
      arm64: entry: improve data abort handling of tagged pointers
      arm64: documentation: document tagged pointer stack constraints

Mark Rutland (6):
      arm64: xchg: hazard against entire exchange variable
      arm64: ensure extension of smp_store_release value
      arm64: uaccess: ensure extension of access_ok() addr
      arm64: armv8_deprecated: ensure extension of addr
      arm64: atomic_lse: match asm register sizes
      arm64: uaccess: suppress spurious clang warning
