Merge tag 'mm-hotfixes-stable-2024-04-26-13-30' of git://git./linux/kernel/git/akpm/mm

Pull misc fixes from Andrew Morton:
 "11 hotfixes. 8 are cc:stable and the remaining 3 (nice ratio!) address
  post-6.8 issues or aren't considered suitable for backporting.

  All except one of these are for MM. I see no particular theme - it's
  singletons all over"
