Yes. The whole terminology is confusing for historical reasons. If we started again with the naming game there would be probably different names.
To make it even more confusing while it is different internally in the kernel, CPUID and /proc/cpuinfo fake them to the same to the world to be compatible with old software who e.g. reads this for licensing purposes.
BTW I doubt these are related to the hang you are chasing because if you grep the kernel cpu_core_map is never used in the kernel at all except for cpuinfo. This means it is unlikely to cause any hangs.
