   - KVM and Xen ports to AArch64
   - Hugetlbfs and transparent huge pages support for arm64
   - Applied Micro X-Gene Kconfig entry and dts file
   - Cache flushing improvements

  For arm64 huge pages support, there are x86 changes moving part of
  arch/x86/mm/hugetlbpage.c into mm/hugetlb.c to be re-used by arm64"
