When this bit is set and transition from 0 to 1, Integrated I/O dispatches a
MCA interrupt defined in the error MCA configuration register to the
processor. This bit is cleared by hardware when Integrated I/O has
dispatched MCA to the Intel QuickPath Interconnect link.
This bit should never be set since the processor does not support MCA
