[RFC][PATCH 0/4] perf: Enable symbolic event names

[Sukadev Bhattiprolu]

Implement ability to specify Power PMU events by their symbolic event
names rather than raw codes. This approach pulls tables of the Power7
and Power8 PMU events into the perf source tree and uses these tables
to create aliases for the PMU events. With these aliases users can run:

	perf stat -e PM_1PLUS_PPC_CMPL:ku sleep 1
or
	perf stat -e cpu/PM_VSU_SINGLE/ sleep 1

This is an early POC patchset based on discussions with Jiri Olsa,
Michael Ellerman and Ingo Molnar. Lightly tested on Power7 and Power8.

Can other architectures can implement arch_get_events_table() and similarly 
use symoblic event names?

I am also assuming that if the header files like power8-events.h are
easily readable, we don't need the JSON files anymore?

TODO:
	- Maybe translate event names to lower-case?
	- Allow perf to process event descriptions (need Andi Kleen's patch)
