[GIT PULL] ARM perf updates for 3.17

[GIT PULL] ARM perf updates for 3.17

[Will Deacon]

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
