  The do_numa_pages only handle non-compound page, and only PMD-mapped THP
is handled in do_huge_pmd_numa_page(), but large, PTE-mapped folio will
be supported, let's convert more numa balancing functions to use/take a
folio in preparation for that, no functional change intended for now.

v2:
- re-order the patch, drop 'extern' and wrap to 80 columns,
  suggested by Matthew
- rename vm_normal_pmd_folio to vm_normal_folio_pmd and fix cpupid,
  suggested by Huang, Ying

Kefeng Wang (6):
  mm: memory: add vm_normal_folio_pmd()
  mm: huge_memory: use a folio in do_huge_pmd_numa_page()
  mm: memory: use a folio in do_numa_page()
  mm: memory: make numa_migrate_prep() to take a folio
  mm: mempolicy: make mpol_misplaced() to take a folio
  sched/numa, mm: make numa migrate functions to take a folio
