Hi Linus,

Please pull the arm64 updates for 4.14 below. There is a minor conflict
in arch/arm64/kernel/fpsimd.c, resolved to the changes introduced in
this pull request (use local_bh_* instead of preempt_*). Thanks.


The following changes since commit aae4e7a8bc44722fe70d58920a36916b1043195e:

  Linux 4.13-rc4 (2017-08-06 18:44:49 -0700)

are available in the git repository at:

  arm64: cleanup {COMPAT_,}SET_PERSONALITY() macro (2017-08-22 18:41:47 +0100)

----------------------------------------------------------------
arm64 updates for 4.14:

- VMAP_STACK support, allowing the kernel stacks to be allocated in
  the vmalloc space with a guard page for trapping stack overflows. One
  of the patches introduces THREAD_ALIGN and changes the generic
  alloc_thread_stack_node() to use this instead of THREAD_SIZE (no
  functional change for other architectures)

- Contiguous PTE hugetlb support re-enabled (after being reverted a
  couple of times). We now have the semantics agreed in the generic mm
  layer together with API improvements so that the architecture code can
  detect between contiguous and non-contiguous huge PTEs

- Initial support for persistent memory on ARM: DC CVAP instruction
  exposed to user space (HWCAP) and the in-kernel pmem API implemented

- raid6 improvements for arm64: faster algorithm for the delta syndrome
  and implementation of the recovery routines using Neon

- FP/SIMD refactoring and removal of support for Neon in interrupt
  context. This is in preparation for full SVE support

- PTE accessors converted from inline asm to cmpxchg so that we can
  use LSE atomics if available (ARMv8.1)

- Perf support for Cortex-A35 and A73

- Non-urgent fixes and cleanups
