Merge tag 'mm-hotfixes-stable-2026-08-06-18-44' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM fixes from Andrew Morton:
 "17 hotfixes.  15 are cc:stable.  16 are for MM.

  There's a patch series from Lorenzo "mm: fix UAF caused by race
  between ptdump and vmap pgtable freeing" which addresses a quite old
  bug in the ptdump code.

  And another series also from Lorenzo which fixes a four year old bug
  in the huge_zero_folio handling.

  A series from SJ fixes a few possible divide-by-zero issues which
  Sashiko sniffed out. And a series which fixes handling of the
  commit_inputs parameters.

  The remainder are singletons, please see their changelogs for details"
