mm: memory: add vm_normal_folio_pmd()
Patch series "mm: convert numa balancing functions to use a folio", v2. do_numa_pages() only handles non-compound pages, and only PMD-mapped THPs are handled in do_huge_pmd_numa_page(). But a large, PTE-mapped folio will be supported so let's convert more numa balancing functions to use/take a folio in preparation for that, no functional change intended for now. This patch (of 6): The new vm_normal_folio_pmd() wrapper is similar to vm_normal_folio(), which allow them to completely replace the struct page variables with struct folio variables.
