Merge tag 'mm-hotfixes-stable-2025-07-11-16-16' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull misc fixes from Andrew Morton:
 "19 hotfixes. A whopping 16 are cc:stable and the remainder address
  post-6.15 issues or aren't considered necessary for -stable kernels.

  14 are for MM.  Three gdb-script fixes and a kallsyms build fix"
