Pull audit update from Eric Paris:
 "Again we stayed pretty well contained inside the audit system.
  Venturing out was fixing a couple of function prototypes which were
  inconsistent (didn't hurt anything, but we used the same value as an
  int, uint, u32, and I think even a long in a couple of places).

  We also made a couple of minor changes to when a couple of LSMs called
  the audit system.  We hoped to add aarch64 audit support this go
  round, but it wasn't ready.

  I'm disappearing on vacation on Thursday.  I should have internet
  access, but it'll be spotty.  If anything goes wrong please be sure to
  cc rgb@redhat.com.  He'll make fixing things his top priority"
