Pull slab updates from Vlastimil Babka:
 "The most prominent change this time is the kmem_buckets based
  hardening of kmalloc() allocations from Kees Cook.

  We have also extended the kmalloc() alignment guarantees for
  non-power-of-two sizes in a way that benefits rust.

  The rest are various cleanups and non-critical fixups.

   - Dedicated bucket allocator (Kees Cook)

     This series [1] enhances the probabilistic defense against heap
     spraying/grooming of CONFIG_RANDOM_KMALLOC_CACHES from last year.

     kmalloc() users that are known to be useful for exploits can get
     completely separate set of kmalloc caches that can't be shared with
     other users. The first converted users are alloc_msg() and
     memdup_user().

     The hardening is enabled by CONFIG_SLAB_BUCKETS.

     For years now we have guaranteed natural alignment for power-...
