Merge tag 'audit-pr-20190507' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit

Pull audit updates from Paul Moore:
 "We've got a reasonably broad set of audit patches for the v5.2 merge
  window, the highlights are below:

   - The biggest change, and the source of all the arch/* changes, is
     the patchset from Dmitry to help enable some of the work he is
     doing around PTRACE_GET_SYSCALL_INFO.

     To be honest, including this in the audit tree is a bit of a
     stretch, but it does help move audit a little further along towards
     proper syscall auditing for all arches, and everyone else seemed to
     agree that audit was a "good" spot for this to land (or maybe they
     just didn't want to merge it? dunno.).

   - We can now audit time/NTP adjustments.

   - We continue the work to connect associated audit records into a
     single event"
