Bug Description

I have tested iks test suite on linux-linaro mp build 301 which is proposed for 13.05 release.
https://android-build.linaro.org/builds/~linaro-android/vexpress-linaro-mp/#build=301

big.LITTLE IKS test suite reported 4 failures related to perf test cases. where it failed to count (or print) events on A15 cluster.

perf-mem-stress-switching : FAIL
perf-disk-io-stress-a7 : FAIL

Maintaining the existing perf support for IKS has become an effort sink.

Since the existing implementation is not suitable for upstream, I am working on rebuilding the functionality on top of a more mainline-oriented perf series.

This should lead to a simpler and more robust implementation.
