KVM: PPC: e500: Support large page mappings of PFNMAP vmas.
This allows large pages to be used on guest mappings backed by things like /dev/mem, resulting in a significant speedup when guest memory is mapped this way (it's useful for directly-assigned MMIO, too). This is not a substitute for hugetlbfs integration, but is useful for configurations where devices are directly assigned on chips without an IOMMU -- in these cases, we need guest physical and true physical to match, and be contiguous, so static reservation and mapping via /dev/mem is the most straightforward way to set things up.
