Current pmd_to_page(), which derives the page table page containing the pmd address has a very misleading name. The problem being, it sounds similar to pmd_page() which derives page embedded in a given pmd entry either for next level page or a mapped huge page. Rename it as pmd_pgtable_page() instead.
