This should speed up accessing new system calls introduced with
the kernel rather than waiting for libaudit updates to include
them.
Committer testing:
$ rm -rf /tmp/build/perf
$ mkdir /tmp/build/perf
$ make srctree=/home/acme/git/perf -C tools/perf/arch/s390 OUTPUT=/tmp/build/perf/ archheaders

Now to plug this into 'perf trace' proper.
