I have to say I think that's pretty ridiculous for someone who cares so
much about size that they have disabled CONFIG_PCI that they can just
add another half-kilobyte of code that is going to do absolutely
nothing.  Think about the kind of x86 CPUs that could even consider
disabling CONFIG_PCI -- we're talking pretty deep embedded by now.

So, no, I don't think this is an option.  Force-enabling CONFIG_PCI on
x86 would be a more realistic option, and I honestly don't know how many
people would object to that, but not right now.

The obvious answer instead is to augment the list of stubs in
<asm/k8.h>.  In particular, move num_k8_northbridges into the #ifdef and
just #define num_k8_northbridges 0 in the other clause.
