10 On powerpc, vmemmap deduplication is only used with radix MMU translation. Also11 with a 64K page size, only the devdax namespace with 1G alignment uses vmemmap14 With 2M PMD level mapping, we require 32 struct pages and a single 64K vmemmap16 vmemmap deduplication possible.19 vmemmap page can contain 1024 struct pages (64K/sizeof(struct page)). Hence we20 require 16 64K pages in vmemmap to map the struct page for 1G PUD level mapping.47 4K vmemmap page contains 64 struct pages(4K/sizeof(struct page)). Hence we48 require 8 4K pages in vmemmap to map the struct page for 2M pmd level mapping.75 vmemmap page can contain 64 struct pages (4K/sizeof(struct page)). Hence we76 require 4096 4K pages in vmemmap to map the struct pages for 1G PUD level
