I realized there was a typo for one of the MSR (MSR_CORE_PERF_FIXED_CTR_CTRL).
Here is a resubmit of the same patch. The i386 also has the typo. Sorry about that.

changelog:
 	- add Intel Precise-Event Based sampling (PEBS) related MSR
	- add Intel Data Save (DS) Area related MSR
	- add Intel Core microarchitecure performance counter MSRs
