Merge tag 'audit-pr-20170907' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:
 "A small pull request for audit this time, only four patches and only
  two with any real code changes.

  Those two changes are the removal of a pointless SELinux AVC
  initialization audit event and a fix to improve the audit timestamp
  overhead.

  The other two patches are comment cleanup and administrative updates,
  nothing very exciting.

  Everything passes our tests"
