35  * Generic x86 cpu ereports.

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