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 from Arnaldo Carvalho de Melo:

User visible changes:

  - Move toggling event logic from 'perf top' and into hists browser, allowing
    freeze/unfreeze with event lists with more than one entry (Namhyung Kim)

  - Add missing newlines when dumping PERF_RECORD_FINISHED_ROUND and
    showing the Aggregated stats in 'perf report -D' (Adrian Hunter)

Infrastructure changes:

  - Allow auxtrace data alignment (Adrian Hunter)

  - Allow events with dot (Andi Kleen)

  - Fix failure to 'perf probe' events on arm (He Kuang)

  - Add testing for Makefile.perf (Jiri Olsa)

  - Add test for make install with prefix (Jiri Olsa)

  - Fix single target build dependency check (Jiri Olsa)

  - Access thread_map entries via accessors, prep patch to hold more info per
    entry, for ongoing 'perf stat --per-thread' work (Jiri Olsa)

  - Use __weak definition from compiler.h (Sukadev Bhattiprolu)

  - Split perf_pmu__new_alias() (Sukadev Bhattiprolu)
