Michal Hocko 97557d1615 selinux: use GFP_NOWAIT in the AVC kmem_caches 
commit 476accbe2f6ef69caeebe99f52a286e12ac35aee upstream.

There is a strange __GFP_NOMEMALLOC usage pattern in SELinux,
specifically GFP_ATOMIC | __GFP_NOMEMALLOC which doesn't make much
sense.  GFP_ATOMIC on its own allows to access memory reserves while
__GFP_NOMEMALLOC dictates we cannot use memory reserves.  Replace this
with the much more sane GFP_NOWAIT in the AVC code as we can tolerate
memory allocation failures in that code.
