Re: [PATCH 4/4] perf: Add power8 PMU events in JSON format

The power8.json and 004d0100.json files describe the PMU events in the
Power8 processor.

The jevents program from the prior patches will use these JSON files
to create tables which will then be used in perf to build aliases for
PMU events. This in turn would allow users to specify these PMU events
by name:

	$ perf stat -e pm_1plus_ppc_cmpl sleep 1

Can't we remove PublicDescription field if it's identical to
BriefDescription?  It seems just wasting spaces..
