intel_pstate: Add X86_FEATURE_APERFMPERF to cpu match parameters. KVM environments do not support APERF/MPERF MSRs. intel_pstate cannot operate without these registers. The previous validity checks in intel_pstate_msrs_not_valid() are insufficent in nested KVMs. References: https://bugzilla.redhat.com/show_bug.cgi?id=1046317 Signed-off-by: Dirk Brandewie <dirk.j.brandewie@intel.com> Cc: All applicable <stable@vger.kernel.org> Signed-off-by: Rafael J.
