Machine Check Error information from struct mce is exported to userspace through the mce_record tracepoint. Currently, however, the PPIN (Protected Processor Inventory Number) field of struct mce is not exported through the tracepoint. Export PPIN through the tracepoint as it may provide useful information for debug and analysis.
