Here's a couple of fixes for KVM/arm64:

- The first one addresses a misinterpretation of the architecture
  spec, leading to the mishandling of I/O accesses generated from an
  AArch32 guest using banked registers.

- The second one is a workaround for a Cortex-A57 erratum.

Both patches are based on v4.4-rc1.
