[RFC PATCH 0/5] perf: Intel uncore pmu counting support

[Yan, Zheng]

Hi, all

Here is the RFC patches to add uncore counting support for Nehalem,
Sandy Bridge and Sandy Bridge-EP, applied on top of current tip.
The code is based on Lin Ming's old patches.

You can use 'perf stat' to access to the uncore pmu. For example:
perf stat -a -C 0 -e 'uncore_nhm/config=0xffff/' sleep 1

For Nehalem and Sandy Bridge-EP, A few general events are exported
under directory:
/sys/bus/event_source/devices/uncore_xxx/events/

Any comment is appreciated.
Thank you
