I would prefer to simply use the existing physical id for this like
in your original patch.  We already have a bewildering zoo of different
CPU IDs, no need to increase the confusion even more.

Incidentially mcelog already knows how to use physical ID for this,
would need to be changed for a new sysfs interface
