[PATCH] x86-64: x86-64 add Intel Core related PMU MSRs definitions
Add o the x86-64 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 for i386 will follow. 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 Signed-off-by: stephane eranian <eranian@hpl.hp.com> Signed-off-by: Andi Kleen <ak@suse.de>
