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

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

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
