The following changes since commit 5ac76283b32b116c58e362e99542182ddcfc8262:

  perf build: Align the names of the build tests: (2016-01-29 17:51:04 -0300)


New features:

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

Infrastructure:

- 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)

  perf tools: By default use the most precise "cycles" hw counter available 
(2015-09-30 18:34:39 -0300)


perf/core improvements and fixes:

User visible:

- By default use the most precise "cycles" hw counter available, i.e.
  when the user doesn't specify any event, it will try using cycles:ppp,
  cycles:pp, etc (Arnaldo Carvalho de Melo)

- Remove blank lines, headers when piping output in 'perf list', so that it can
  be sanely used with 'wc -l', etc (Arnaldo Carvalho de Melo)

- Amend documentation about max_stack and synthesized callchains (Adrian Hunter)

- Fix 'perf probe -l' for probes added to kernel module functions (Masami 
Hiramatsu)

Build fixes:

- Fix shadowed declarations that break the build on older distros (Jiri Olsa)

- Fix build break on powerpc due to sample_reg_masks (Sukadev Bhattiprolu)
