Quoting the respective Linux commit:
Intel Xeons from Ivy Bridge onwards support a processor identification
number set in the factory. To the user this is a handy unique number to
identify a particular CPU. Intel can decode this to the fab/production
run to track errors. On systems that have it, include it in the machine
check record. I'm told that this would be helpful for users that run
large data centers with multi-socket servers to keep track of which CPUs
are seeing errors.
Newer AMD CPUs support this too, at different MSR numbers.
Take the opportunity and hide __MC_NMSRS from the public interface going
forward.
