Merge tag 'perf-core-for-mingo-3' 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:
User visible changes:
- Improve --filter support for 'perf probe', allowing using its arguments
on other commands, as --add, --del, etc (Masami Hiramatsu)
- Show warning when running 'perf kmem stat' on a unsuitable perf.data file,
i.e. one with events that are not the ones required for the stat variant
used (Namhyung Kim).
Infrastructure changes:
- Auxtrace support patches, paving the way to support Intel PT and BTS (Adrian Hunter)
- hists browser (top, report) refactorings (Namhyung Kim)
