[kvm-devel] [PATCH] MSR_IA32_PERF_STATUS support

[Alexander G. <al...@cs...>]

This patch adds support for the MSR MSR_IA32_PERF_STATUS. This is
required to boot Darwin.

I only implemented dummy support, as the real value would be of no
meaning to any OS I know so far anyway and is only implemented on very
recent Intel CPUs.
