QEMU already supports these hypercalls so this is just an optimization. Both HV and PR KVM modes are supported. This does not affect VFIO, this support is coming next. This includes "powerpc: Make vmalloc_to_phys() public" as the patch depends on it. The individual patches have changelog. This is based on sha1 c05235d (kernelrelease = v4.5.0-rc3). Please comment. Thanks.
