Merge tag 'slab-for-7.0-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull more slab updates from Vlastimil Babka:

 - Two stable fixes for kmalloc_nolock() usage from NMI context (Harry
   Yoo)

 - Allow kmalloc_nolock() allocations to be freed with kfree() and thus
   also kfree_rcu() and simplify slabobj_ext handling - we no longer
   need to track how it was allocated to use the matching freeing
   function (Harry Yoo)

* tag 'slab-for-7.0-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab:
  mm/slab: drop the OBJEXTS_NOSPIN_ALLOC flag from enum objext_flags
  mm/slab: allow freeing kmalloc_nolock()'d objects using kfree[_rcu]()
  mm/slab: use prandom if !allow_spin
  mm/slab: do not access current->mems_allowed_seq if !allow_spin
