    Subject[PATCH 3/6] KVM: SVM: Drop VMXE check from svm_set_cr4()
    Date
    Drop svm_set_cr4()'s explicit check CR4.VMXE now that common x86 handles
    the check by incorporating VMXE into the CR4 reserved bits, via
    kvm_cpu_caps. SVM obviously does not set X86_FEATURE_VMX.

    No functional change intended.
