    x86, UV: Fix NMI handler for UV platforms · 1d44e828
    Jack Steiner authored
    This fixes problems seen on UV systems handling NMIs from the
    node controller.
    
    I isolated the "dazed..." messages that I saw earlier to a bug in
    the BMC on our platform. It was sending NMIs w/o properly setting
    a register that indicated the source of NMI.
    
    So rather than _assuming_ any unhandled NMI came from the UV system
    maintenance console (SMC), add a check to verify that the SMC actually
    sent the NMI.
