[PATCH v3 00/10] mm: convert mm counter to take a folio

Make sure all mm_counter() and mm_counter_file() callers have a folio,
then convert mm counter functions to take a folio, which saves some
compound_head() calls.

v3:
- Rebase on top of my similar patch to add pfn_swap_entry_folio()
- Various wordsmithing & notes about where we're actually saving
calls to compound_head().

v2:
- rebase on v6.7, since most of mm counter callers already with a folio,
drop some unneeded changes.

v1:
- rename should_zap_page() to should_zap_folio(), per Matthew Wilcox
- pass page to page_remove_rmap/page_try_dup_anon_rmap for
device private page, per Matthew Wilcox

Kefeng Wang (7):
s390: use pfn_swap_entry_folio() in ptep_zap_swap_entry()
mm: use pfn_swap_entry_folio() in __split_huge_pmd_locked()
mm: use pfn_swap_entry_to_folio() in zap_huge_pmd()
mm: use pfn_swap_entry_folio() in copy_nonpresent_pte()
mm: Convert to should_zap_page() to should_zap_folio()
mm: convert mm_counter() to take a folio
mm: convert mm_counter_file() to take a folio
