Currently, the microcode field (Microcode Revision) of 'struct mce' is not exposed to userspace through the mce_record tracepoint. Knowing the microcode version on which the MCE was received is critical information for debugging. If the version is not recorded, later attempts to acquire the version might result in discrepancies since it can be changed at runtime. Add microcode version to the tracepoint to prevent ambiguity over the active version on the system when the MCE was received.
