    Subject[PATCH 3.16 217/245] KVM: nVMX: Don't emulate instructions in guest mode
    3.16.83-rc1 review patch.  If anyone has any objections, please let me know.

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

    From: Paolo Bonzini <pbonzini@redhat.com>

    commit 07721feee46b4b248402133228235318199b05ec upstream.

    vmx_check_intercept is not yet fully implemented. To avoid emulating
    instructions disallowed by the L1 hypervisor, refuse to emulate
    instructions by default.
