Pull audit updates from Paul Moore:
 "A small set of patches for audit this time; just three in total and
  one is a spelling fix.

  The two patches with actual content are designed to help prevent new
  instances of auditd from displacing an existing, functioning auditd
  and to generate a log of the attempt.  Not to worry, dead/stuck auditd
  instances can still be replaced by a new instance without problem.

  Nothing controversial, and everything passes our regression suite"

* 'stable-4.6' of git://git.infradead.org/users/pcmoore/audit:
