shared cache -- Re: SMP detection

[Josh Carroll]

Core 2 Duos have the EM64T extensions. Core Duos (Yonah) are a mobile
chip only, not a full line of processors like the Core 2 architecture
(Merom, Conroe, Woodcrest).

I suspect the Core 2 chips do not suffer from the same security
implications as HT-enabled processors. I'm not certain, but I think
each processor has access to half the cache so the only reason it's
shared is that it's on the same die and both cores are using parts of
it.
