    Subject[PATCH 3.2 01/67] KVM: vmx: fix MPX detection
    3.2.78-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Paolo Bonzini <pbonzini@redhat.com>

    commit 920c837785699bcc48f4a729ba9ee3492f620b95 upstream.

    kvm_x86_ops is still NULL at this point. Since kvm_init_msr_list
    cannot fail, it is safe to initialize it before the call.

    Fixes: 93c4adc7afedf9b0ec190066d45b6d67db5270da
