Merge tag 'perf-core-for-mingo-2' of... 

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

 into perf/core

Pull perf tooling changes from Arnaldo Carvalho de Melo:

New features:

 - Port 'perf kvm stat' to PowerPC (Hemant Kumar)

Infrastructure changes:

 - Use the 'feature-dump' target to do the feature checks just once and then
   add code to reuse that in the tests/make makefile, speeding up the
   'make -C tools/perf build-test' target (Wang Nan)

 - Reduce the number of tests the 'build-test' target do to those that don't
   pollute the source tree (Arnaldo Carvalho de Melo)

 - Improve the output of the build tests a bit by aligning the name of the
   tests, more can be done to filter out uninteresting info in the output
   (Arnaldo Carvalho de Melo)

 - Add perf_evlist pointer to *info_priv_size(), more prep work for
   supporting the coresight architecture (Mathieu Poirier)

 - Improve the 'perf test bp_signal' test (Wang Nan)

 - Check environment before starting the BPF 'perf test', so that we can just
   'Skip' older kernels instead of 'FAIL'ing them (Wang Nan)

 - Fix cpumode of synthesized buildid event (Wang Nan)
