[PATCH v2 2/9] KVM: selftests: Use host_cpu_is_intel_compatible for mediated PMU

[Ewan Hai-oc]

From: Frank Zhu <frankzhu@xxxxxxxxxxx>

kvm_is_mediated_pmu_enabled() returns kvm_amd's enable_mediated_pmu
module parameter unless the host CPU is Intel.  Zhaoxin CPUs implement
VMX-compatible virtualization and are handled by KVM's VMX backend, so
on Zhaoxin hosts the helper wrongly reports kvm_amd's parameter.

Gate the check on host_cpu_is_intel_compatible so that Zhaoxin CPUs,
like Intel CPUs, query kvm_intel's enable_mediated_pmu instead.  This
does not change behavior on Intel, and AMD and other non-Intel-
compatible CPUs still fall back to kvm_amd's parameter.
