37  * Generic x86 cpu ereports.

39  * On a machine-check exception, or on a periodic poll for error status
40  * of a cpu, we read through all the MCA banks of the processor and
41  * log an ereport for each MCA bank that contains valid error telemetry.
42  * These ereports will all share the same detector FMRI and ENA.
43  *
44  * Since we have no model-specific knowledge of the cpu we cannot
45  * decode all details of the error, so we'll stick to the "architectural"
46  * bits.  Similarly since we have no associated memory-controller driver
47  * or detailed topology information we cannot produce "resource" ereport
48  * FMRIs.
