/*
 * Generic x86 cpu ereports.
 *
 * On a machine-check exception, or on a periodic poll for error status
 * of a cpu, we read through all the MCA banks of the processor and
 * log an ereport for each MCA bank that contains valid error telemetry.
 * These ereports will all share the same detector FMRI and ENA.
 *
 * Since we have no model-specific knowledge of the cpu we cannot
 * decode all details of the error, so we'll stick to the "architectural"
 * bits.  Similarly since we have no associated memory-controller driver
 * or detailed topology information we cannot produce "resource" ereport
 * FMRIs.
