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?
