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"
