Merge tag 'perf-core-for-mingo-4.17-20180319' of git://git./linux/kernel/git/acme/linux into perf/core

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

- Fixes for problems experienced with new GCC 8 warnings, that treated
  as errors, broke the build, related to snprintf and casting issues.
  (Arnaldo Carvalho de Melo, Jiri Olsa, Josh Poinboeuf)

- Fix build of new breakpoint 'perf test' entry with clang < 6, noticed
  on fedora 25, 26 and 27 (Arnaldo Carvalho de Melo)

- Workaround problem with symbol resolution in 'perf annotate', using
  the symbol name already present in the objdump output (Arnaldo Carvalho de Melo)

- Document 'perf top --ignore-vmlinux' (Arnaldo Carvalho de Melo)

- Fix out of bounds access on array fd when cnt is 100 in one of the
  'perf test' entries, detected using 'cpptest' (Colin Ian King)

- Add support for the forced leader feature, i.e. 'perf report --group'
  for a group of events not really grouped when scheduled (without using
  {} to enclose the list of events in the command line) in pipe mode,
  e.g.:

    $ perf record -e cycles,instructions -o - kill | perf report --group -i -

- Use right type to access array elements in 'perf probe' (Masami Hiramatsu)

- Update POWER9 vendor events (those described in JSON format) (Sukadev Bhattiprolu)

- Discard head in overwrite_rb_find_range() (Yisheng Xie)

- Avoid setting 'quiet' to 'true' unnecessarily (Yisheng Xie)
