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: http://marc.info/?l=kvm&m=138074894126934&w=2 The whole thing can also be cloned from here: git://git.linaro.org/people/cdall/linux-kvm-arm.git kvm-arm-hugepages-v3 See the patches for changelogs.
