Since cpu_name is local, not referenced, and not next to anything
noteworthy (so, unlikely to be found implicitly), I wonder why it's
needed at all.

cputable.c:cpu_table just has a C string literal instead, with the same
content.

Perhaps proc.S:cpu_name is used in some other way, but I can't see it.
The kernel still builds if it is deleted.

Cheers
