Hi, all

This is the v2 patches to support uncore pmu counting.
The most important change is to use hrtimer to pull uncore counters
to handle overflow, because uncore pmu interrupt does not work.

v2 -> v1:
- Use hrtimer to pull counters
- Add interface to add general events to sysfs
- Move MSRs to msr-index.h
- Add uncore fixed counter
- Allow system-wide 'perf stat' without 'command'

Comments are appreciated.

Thanks,
Lin Ming
