From: Jim Mattson <jmattson@xxxxxxxxxx> KVM must verify both host support and guest CPUID enumeration before enabling guest access to APERFMPERF. This verification is deferred until the implementation of guest APERFMPERF is complete. This declaration enables "guest_can_use(vcpu, X86_FEATURE_APERFMPERF)". Otherwise, that expression results in a compile-time error.
