Pull audit updates from Paul Moore:
"Six audit patches for 4.8.
There are a couple of style and minor whitespace tweaks for the logs,
as well as a minor fixup to catch errors on user filter rules, however
the major improvements are a fix to the s390 syscall argument masking
code (reviewed by the nice s390 folks), some consolidation around the
exclude filtering (less code, always a win), and a double-fetch fix
for recording the execve arguments"
