Merge tag 'mm-hotfixes-stable-2026-05-18-21-07' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull misc fixes from Andrew Morton:
 "14 hotfixes. 9 are for MM. 10 are cc:stable and the remainder are for
  post-7.1 issues or aren't deemed suitable for backporting.

  There's a two-patch MAINTAINERS series from Mike Rapoport which
  updates us for the new KEXEC/KDUMP/crash/LUO/etc arrangements. And
  another two-patch series from Muchun Song to fix a couple of
  memory-hotplug issues. Otherwise singletons, please see the changelogs
  for details"
