Merge tag 'perf-core-for-mingo-4.13-20170630' 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:

Intel PT enhancements:

 - Support "ptwrite" instruction, a way to stuff 32 or 64 bit values into
   the Intel PT trace (Adrian Hunter)

 - Support power events in Intel PT to report changes to C-state (Adrian
   Hunter)

 - Synthesize Intel PT events as PERF_RECORD_SAMPLE records with a
   perf_event_attr.type (PERF_TYPE_SYNTH) just after the range used by the
   kernel, i.e. right after what is allocated for PMUs, at INT_MAX + 1U,
   attr.config will have the identification for the synthesized event and
   the PERF_SAMPLE_RAW payload will have its fields (Adrian Hunter)

Infrastructure changes:

 - Remove warning() and error(), using instead pr_warning() and
   pr_error(), consolidating error reporting (Arnaldo Carvalho de Melo)

 - Add platform dependency to 'perf test 15' (Thomas Richter)
