Kirill A. Shutemov 93b4796ded thp: do_huge_pmd_wp_page(): handle huge zero page ... On write access to huge zero page we alloc a new huge page and clear it. If ENOMEM, graceful fallback: we create a new pmd table and set pte around fault address to newly allocated normal (4k) page. All other ptes in the pmd set to normal zero page.
