ARM perf updates for 3.17

Hi Russell,

Please can you pull the following perf updates for 3.17? You will get a trivial conflict with your MIDR rework, but SFR fixed that up correctly already in -next [1].

The main changes are:

- Callchain stability fixes from Jean Pihet
- Event mapping and PMU name rework from Mark Rutland

The latter is preparatory work for enabling some code re-use with arm64 in the future.

Cheers,

Will
