Merge tag 'perf-core-for-mingo-4.14-20170814' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

Infrastructure changes:

- Do not consider empty files as valid srclines (Milian Wolff)

- Fix wrong size in perf_record_mmap for last kernel module,
  which resulted in erroneous symbol resolution in at least s390x (Thomas Richter)

- Add missing newline to expr parser error messages (Andi Kleen)

- Fix saved values rbtree lookup in 'perf stat' (Andi Kleen)

- Add support for shell based tests in 'perf test', add a few that
  run 'perf probe', 'perf trace', using kprobes, uprobes to check
  the output of those tools and the effects on the system, checking,
  for instance, DWARF backtraces from uprobes (Arnaldo Carvalho de Melo)

Arch specific changes:

- Add ppc64le to audit uname list in the python scripting support (Naveen N. Rao)

- Update POWER9 vendor events tables (Sukadev Bhattiprolu)

- Fix module symbol adjustment for s390x (Thomas Richter)
