Merge tag 'mm-hotfixes-stable-2025-09-10-20-00' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull misc fixes from Andrew Morton:
 "20 hotfixes. 15 are cc:stable and the remainder address post-6.16
  issues or aren't considered necessary for -stable kernels. 14 of these
  fixes are for MM.

  This includes

   - kexec fixes from Breno for a recently introduced
     use-uninitialized bug

   - DAMON fixes from Quanmin Yan to avoid div-by-zero crashes
     which can occur if the operator uses poorly-chosen insmod
     parameters

   and misc singleton fixes"
