> ghes_do_proc() has a catch-all for unknown or unhandled CPER formats (UEFI
> v2.10 Appendix N 2.3), extlog_print() does not. This gap was noticed by a RAS
> test that injected CXL protocol errors which were notified to extlog_print() via
> the IOMCA (I/O Machine Check
> Architecture) mechanism. Bring parity to the extlog_print() path by including a
> similar log_non_standard_event().
