Merge branch 'stable-4.9' of git://git.infradead.org/users/pcmoore/audit

Pull audit updates from Paul Moore:
 "Another relatively small pull request for v4.9 with just two patches.

  The patch from Richard updates the list of features we support and
  report back to userspace; this should have been sent earlier with the
  rest of the v4.8 patches but it got lost in my inbox.

  The second patch fixes a problem reported by our Android friends where
  we weren't very consistent in recording PIDs"

* 'stable-4.9' of git://git.infradead.org/users/pcmoore/audit:
  audit: add exclude filter extension to feature bitmap
  audit: consistently record PIDs with task_tgid_nr()
