Pull MM fixes from Andrew Morton:
 "20 hotfixes. All are for MM (and for MMish maintainers). 9 are
  cc:stable and the remainder are for post-7.0 issues or aren't deemed
  suitable for backporting.

  There are two DAMON series from SeongJae Park which address races
  which could lead to use-after-free errors, and avoid the possibility
  of presenting stale parameter values to users"
