Technically, you're correct. But I don't think the extra declaration
hurts anything. It is a platform-independent file, so I'm reluctant
to add an #ifdef. I am working on getting the per-CPU data changes
accepted into the main line tree, but the going is very slow (Linus is
focusing on the bio stuff). Actually, if someone has a good idea of
implementing fast local access to per-CPU data on x86, I'm all ears,
as this would help getting the changes accepted into the main tree. I
assume the Sequent/IBM folks have solved this problem for their x86
NUMA machines already?
