| "name" as:
| 
|       perf stat -e pm_1plus_ppc_cmpl sleep 1
| 
| The file, 'tools/perf/pmu-events/README' in [PATCH 16/16] gives more

| Note:
|       - All known events tables for the architecture are included in the
|         perf binary.
| 
|       - For architectures that don't have any JSON files, an empty mapping

Arnaldo, Ingo,

I added Andi's patch https://lkml.org/lkml/2015/8/28/521 to 'json-v16' branch.
and created a new branch, 'json-files-7' with updated to Intel data files.
Here are the three new branches.
