Merge branch 'stable-4.11' of git://git.infradead.org/users/pcmoore/audit

Pull audit cleanup from Paul Moore:
 "A week later than I had hoped, but as promised, here is the audit
  uninline-fix we talked about during the last audit pull request.

  The patch is slightly different than what we originally discussed as
  it made more sense to keep the audit_signal_info() function in
  auditsc.c rather than move it and bunch of other related
  variables/definitions into audit.c/audit.h.

  At some point in the future I need to look at how the audit code is
  organized across kernel/audit*, I suspect we could do things a bit
  better, but it doesn't seem like a -rc release is a good place for
  that ;)

  Regardless, this patch passes our tests without problem and looks good
  for v4.11"
