Make all mm_counter() and mm_counter_file() callers to use a folio,
then convert mm counter functions to take a folio, which saves lots
of compound_head() calls.

Kefeng Wang (10):
mm: swap: introduce pfn_swap_entry_to_folio()
s390: pgtable: use a folio in ptep_zap_swap_entry()
mm: huge_memory: use a folio in __split_huge_pmd_locked()
mm: huge_memory: use a folio in zap_huge_pmd()
mm: memory: use a folio in copy_nonpresent_pte()
mm: memory: use a folio in zap_pte_range()
mm: memory: use a folio in do_set_pmd()
mm: memory: use a folio in insert_page_into_pte_locked()
mm: convert mm_counter() to take a folio
mm: convert mm_counter_file() to take a folio
