Changes since v4:
* Rebase onto perf/core
* Convert new perf_pmu__cpu_slots_per_cycle() function to use
new helper functions
===========================
Changes since v3:
* Scale time estimates by INSTR_PER_NS, rather than assuming 1
instruction = 1ns
* Add a new commit that fixes some issues around timestamps going
backwards
* Use nanoseconds inside cs-etm-decoder.c, rather than storing the
raw time values and converting when a sample is synthesized. This
simplifies some of the code like estimating the first timestamp.
===========================
Changes since v2:
* Remove const to non-const change and copy strings where needed
instead.
* Use sizeof() instead of PATH_MAX
* Append "will not be set accurately." to new error message
* Remove unneeded stat() call
* Rebase on perf/core
==========================
Changes since v1:
* Add 3 refactor commits for sysfs reading around pmu.c as suggested
by Arnaldo here [1]
* The dependency on [2] has now reached mainline so is no longer
blocking
* Rebase on perf/core

German Gomez (4):
perf pmu: Add function to check if a pmu file exists
perf cs_etm: Keep separate symbols for ETMv4 and ETE parameters
perf cs_etm: Record ts_source in AUXTRACE_INFO for ETMv4 and ETE
perf cs_etm: Set the time field in the synthetic samples
James Clark (4):
perf: Remove duplication around EVENT_SOURCE_DEVICE_PATH
perf: Use perf_pmu__open_file() and perf_pmu__scan_file()
perf: Remove remaining duplication of bus/event_source/devices/...
perf: cs-etm: Ensure that Coresight timestamps don't go backwards
