Hi all,

Here are a few small improvements to the compat vDSO and sigpage
implementation for arm64 which I cooked up when comparing the code with
the native 32-bit counterpart.

Cheers,

Will

Will Deacon (5):
  arm64: vdso: Use GFP_KERNEL for allocating compat vdso and signal
    pages
  arm64: vdso: Remove redundant calls to flush_dcache_page()
  arm64: compat: Allow signal page to be remapped
  arm64: vdso: Avoid ISB after reading from cntvct_el0
  arm64: compat: Poison the compat sigpage
