Avadhut Naik 98430645e3 tracing: Add the ::ppin field to the mce_record tracepoint
Machine Check Error information from 'struct mce' is exposed to userspace
through the mce_record tracepoint.

Currently, however, the PPIN (Protected Processor Inventory Number) field
of 'struct mce' is not exposed.

Add a PPIN field to the tracepoint as it provides a unique identifier for
the system (or socket in case of multi-socket systems) on which the MCE
has been received.

Also, add a comment explaining the kind of information that can be and
should be added to the tracepoint.
