Merge tag 'perf-core-for-mingo-20161028' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
perf/core improvements and fixes from Arnaldo Carvalho de Melo:
New features:
- Support matching by topic in 'perf list' (Andi Kleen)
User visible:
- Apply cpu color only when there was activity in 'perf sched map' (Namhyung Kim)
- Always show the task's COMM in 'perf sched map -v' (Namhyung Kim)
- Fix hierarchy column counts in the perf hist browser (top, report), avoiding
showing nothing after pressing the RIGHT key a number of times (Namhyung Kim)
Infrastructure:
- Support cascading options in libsubcmd and use it to share common options in
'perf sched' subcommands (Namhyung Kim)
- Avoid worker cacheline bouncing in 'perf bench futex' (Davidlohr Bueso)
- Sanitize numeric parameters in 'perf bench futex' (Davidlohr Bueso)
- Update copies of kernel files (Arnaldo Carvalho de Melo)
- Fix scripting (perl, python) setup to avoid leaks (Arnaldo Carvalho de Melo)
- Add missing object file to the python binding linkage list (Arnaldo Carvalho de Melo)
