  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_reset_last(), page_cpupid_xchg_last(), xchg_page_access_time(),
and page_cpupid_last() are converted to folio one.

Kefeng Wang (9):
  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()
  mm: page_alloc: use a folio in free_pages_prepare()
  mm: convert page_cpupid_reset_last() to folio_cpupid_reset_last()
