Linus Torvalds 714d8e7e27 arm64 updates for 4.1: 
The main change here is a significant head.S rework that allows us to
 boot on machines with physical memory at a really high address without
 having to increase our mapped VA range. Other changes include:
 
 - AES performance boost for Cortex-A57
 - AArch32 (compat) userspace with 64k pages
 - Cortex-A53 erratum workaround for #845719
 - defconfig updates (new platforms, PCI, ...)

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

Pull arm64 updates from Will Deacon:
 "Here are the core arm64 updates for 4.1.

  Highlights include a significant rework to head.S (allowing us to boot
  on machines with physical memory at a really high address), an AES
  performance boost on Cortex-A57 and the ability to run a 32-bit
  userspace with 64k pages (although this requires said userspace to be
  built with a recent binutils).

  The head.S rework spilt over into KVM, so there are some changes under
  arch/arm/ which have been acked by Marc Zyngier (KVM co-maintainer).
  In particular, the linker script changes caused us some issues in
  -next, so there are a few merge commits where we had to apply fixes on
  top of a stable branch.

  Other changes include:

   - AES performance boost for Cortex-A57
   - AArch32 (compat) userspace with 64k pages
   - Cortex-A53 erratum workaround for #845719
   - defconfig updates (new platforms, PCI, ...)"
