[PATCH v3 0/7] perf cs_etm: Basic support for virtual/kernel timestamps

[James Clark]

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
