[Andrew Morton]

The quilt patch titled
     Subject: mm/thp: rename pmd_to_page() as pmd_pgtable_page()
has been removed from the -mm tree.  Its filename was
     mm-thp-rename-pmd_to_page-as-pmd_pgtable_page.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/thp: rename pmd_to_page() as pmd_pgtable_page()
Date: Thu, 24 Nov 2022 18:46:41 +0530

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.
