Hi Viresh,

Please pull the following changes(v2) for the multiple CPU PMU support (re-based to v3.6).

Changes v1->v2: 1. Incorporated review comments from Will for few patches(which he will be queuing for v3.8) 2. Dropped "ARM: perf: register the init functions with the bindings", still looking for alternate to list in implementation. 3. Added per-process event tracking support on multi-PMUs. Re-factored the original patch "ARM: perf: add support for per-cluster/multiple PMUs" 4. Fixed the bug reported by Tixy for non-FDT case
