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)
