This small series adds support for Transparent Huge Pages and hugetlbfs
pages for KVM on the arm and arm64 architectures.

Measurements have shown that using huge pages in for stage-2 mappings
provides up to more than 15% performance increase for some workloads.

The patch series applies to kvm/next, but depends on the patch sent
earlier:

"ARM: KVM: Fix unaligned unmap_range leak"

Christoffer Dall (3):
  KVM: Move gfn_to_index to x86 specific code
  KVM: ARM: Get rid of KVM_HPAGE_XXX defines
  KVM: ARM: Transparent huge pages and hugetlbfs support
