[PATCH 0/9] Various significant MM patches

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

These patches all interact in annoying ways which make it tricky to
send them out in any way other than a big batch, even though there's
not really an overarching theme to connect them.

The big effects of this patch series are:

 - folio_test_hugetlb() becomes reliable, even when called without a
   page reference
 - We free up PG_slab, and we could always use more page flags
 - We no longer need to check PageSlab before calling page_mapcount()

Matthew Wilcox (Oracle) (9):
  mm: Always initialise folio->_deferred_list
  mm: Create FOLIO_FLAG_FALSE and FOLIO_TYPE_OPS macros
  mm: Remove folio_prep_large_rmappable()
  mm: Support page_mapcount() on page_has_type() pages
  mm: Turn folio_test_hugetlb into a PageType
  mm: Remove a call to compound_head() from is_page_hwpoison()
  mm: Free up PG_slab
  mm: Improve dumping of mapcount and page_type
  hugetlb: Remove mention of destructors
