Merge tag 'perf-core-for-mingo-5.4-20190920-2' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

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

perf stat:

  Srikar Dronamraju:

  - Fix a segmentation fault when using repeat forever.

  - Reset previous counts on repeat with interval.

aarch64:

  James Clark:

  - Add PMU event JSON files for Cortex-A76 and Neoverse N1.

PowerPC:

  Anju T Sudhakar:

  - Make 'trace_cycles' the default event for 'perf kvm record' in PowerPC.

S/390:

  - Link libjvmti to tools/lib/string.o to have a weak strlcpy()
    implementation, providing previously unresolved symbol on s/390.

perf test:

  Jiri Olsa:

  - Add libperf automated tests to 'make -C tools/perf build-test'.

  Colin Ian King:

  - Fix spelling mistake.

Tree wide:

  Arnaldo Carvalho de Melo:

  - Some more header file sanitization.

libperf:

  Jiri Olsa:

  - Add dependency on libperf for python.so binding.

libtraceevent:

  Sakari Ailus:

  - Convert remaining %p[fF] users to %p[sS].
