Subject: powerpc: is_hugepage_only_range() must account for both 4kB and 64kB slices

powerpc: is_hugepage_only_range() must account for both 4kB and 64kB slices

powerpc: is_hugepage_only_range() must account for both 4kB and 64kB slices

The subpage_prot syscall fails on second and subsequent calls for a given
region, because is_hugepage_only_range() is mis-identifying the 4 kB
slices when the process has a 64 kB page size.
