Aneesh Kumar K.V f2b79c0d79 powerpc/book3s64/radix: add support for vmemmap optimization for radix ...

With 2M PMD-level mapping, we require 32 struct pages and a single vmemmap
page can contain 1024 struct pages (PAGE_SIZE/sizeof(struct page)).  Hence
with 64K page size, we don't use vmemmap deduplication for PMD-level
mapping.
