All done. Good news (I think): there's no difference in the CPU-related
topology on either system with your patch, aside from kernel build date.
The topologies are still detected correctly. In case you want them:
Supermicro X7SBA
Intel C2D E8400 (stepping 10)

All other systems I have are C2D and C2Q-based, but I can't easily test
on those given their production roles. If there's a particular Intel
processor family/model you're interested in, let me know and I can dig
around to see if I have access to one.
