Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux 

Pull arm64 fixes from Will Deacon:
 "Three arm64 fixes for -rc3.  They're all pretty straightforward: a
  couple of NUMA issues from the Huawei folks and a thinko in
  __page_to_voff that seems to be benign, but is certainly better off
  fixed.

  Summary:
   - couple of NUMA fixes
   - thinko in __page_to_voff"
