Merge branch 'upstream' of git://git.infradead.org/users/pcmoore/audit

Pull audit fixes from Paul Moore:
 "Four patches to fix various problems with the audit subsystem, all are
  fairly small and straightforward.

  One patch fixes a problem where we weren't using the correct gfp
  allocation flags (GFP_KERNEL regardless of context, oops), one patch
  fixes a problem with old userspace tools (this was broken for a
  while), one patch fixes a problem where we weren't recording pathnames
  correctly, and one fixes a problem with PID based filters.

  In general I don't think there is anything controversial with this
  patchset, and it fixes some rather unfortunate bugs; the allocation
  flag one can be particularly scary looking for users"

* 'upstream' of git://git.infradead.org/users/pcmoore/audit:
  audit: restore AUDIT_LOGINUID unset ABI
  audit: correctly record file names with different path name types
  audit: use supplied gfp_mask from audit_buffer in kauditd_send_multicast_skb
  audit: don't attempt to lookup PIDs when changing PID filtering audit rules
