KVM: selftests: Add hugepage support for x86-64
Add x86-64 hugepage support in the form of a x86-only variant of virt_pg_map() that takes an explicit page size. To keep things simple, follow the existing logic for 4k pages and disallow creating a hugepage if the upper-level entry is present, even if the desired pfn matches. Opportunistically fix a double "beyond beyond" reported by checkpatch.
