Merge tag 'folio-5.18e' of git://git.infradead.org/users/willy/pagecache
Pull folio fixes from Matthew Wilcox:
"Fewer bug reports than I was expecting from enabling large folios.
One that doesn't show up on x86 but does on arm64, one that shows up
with hugetlbfs memory failure testing and one that shows up with page
migration, which it turns out I wasn't testing because my last NUMA
machine died. Need to set up a qemu fake NUMA machine so I don't skip
testing that in future.
Summary:
- Remove the migration code's assumptions about large pages being PMD
sized
- Don't call pmd_page() on a non-leaf PMD
- Fix handling of hugetlbfs pages in page_vma_mapped_walk"
* tag 'folio-5.18e' of git://git.infradead.org/users/willy/pagecache:
mm/rmap: Fix handling of hugetlbfs pages in page_vma_mapped_walk
mm/mempolicy: Use vma_alloc_folio() in new_page()
mm: Add vma_alloc_folio()
mm/migrate: Use a folio in migrate_misplaced_transhuge_page()
mm/migrate: Use a folio in alloc_migration_target()
mm/huge_memory: Avoid calling pmd_page() on a non-leaf PMD
