[PATCH -next 0/7] mm: convert page cpupid functions to folios

[Kefeng Wang]

The cpupid(or access time) used by numa balancing is stored in flags
or _last_cpupid(if LAST_CPUPID_NOT_IN_PAGE_FLAGS) of page, this is to
convert page cpupid to folio cpupid, a new _last_cpupid is added into
folio, which make us to use folio->_last_cpupid directly, and the
page_cpupid_xchg_last(), xchg_page_access_time() and page_cpupid_last()
are converted to folio ones.

v1:
- drop inappropriate page_cpupid_reset_last convertion from RFC
- rebased on next-20231009

Kefeng Wang (7):
  mm_types: add _last_cpupid into folio
  mm: mprotect: use a folio in change_pte_range()
  mm: huge_memory: use a folio in change_huge_pmd()
  mm: convert xchg_page_access_time to xchg_folio_access_time()
  mm: convert page_cpupid_last() to folio_cpupid_last()
  mm: make wp_page_reuse() and finish_mkwrite_fault() to take a folio
  mm: convert page_cpupid_xchg_last() to folio_cpupid_xchg_last()
