Merge branch 'stable-4.12' of git://git.infradead.org/users/pcmoore/audit

Pull audit updates from Paul Moore:
 "Fourteen audit patches for v4.12 that span the full range of fixes,
  new features, and internal cleanups.

  We have a patches to move to 64-bit timestamps, convert refcounts from
  atomic_t to refcount_t, track PIDs using the pid struct instead of
  pid_t, convert our own private audit buffer cache to a standard
  kmem_cache, log kernel module names when they are unloaded, and
  normalize the NETFILTER_PKT to make the userspace folks happier.

  From a fixes perspective, the most important is likely the auditd
  connection tracking RCU fix; it was a rather brain dead bug that I'll
  take the blame for, but thankfully it didn't seem to affect many
  people (only one report).

  I think the patch subject lines and commit descriptions do a pretty
  good job of explaining the details and why the changes are important
  so I'll point you there instead of duplicating it here; as usual, if
  you have any questions you know where to find us.

  We also manage to take out more code than we put in this time, that
  always makes me happy :)"
