Subject[PATCH] i386 add Intel Core related PMU MSRs
Hello,

The following patch adds to the i386 tree a bunch of MSRs related to performance
monitoring for the processors based on Intel Core microarchitecture. It also adds
some architectural MSRs for PEBS. A similar patch was posted for x86-64.

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
