Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes:
User visible changes:
- By default use the most precise "cycles" hw counter available, i.e.
when the user doesn't specify any event, it will try using cycles:ppp,
cycles:pp, etc. (Arnaldo Carvalho de Melo)
- Remove blank lines, headers when piping output in 'perf list', so that it can
be sanely used with 'wc -l', etc. (Arnaldo Carvalho de Melo)
- Amend documentation about max_stack and synthesized callchains. (Adrian Hunter)
- Fix 'perf probe -l' for probes added to kernel module functions. (Masami Hiramatsu)
Build fixes:
- Fix shadowed declarations that break the build on older distros. (Jiri Olsa)
- Fix build break on powerpc due to sample_reg_masks. (Sukadev Bhattiprolu)
