It's been a month or two since I trawled through the cpupools code;
but I seem to recall that .init is called twice -- once for the
"default pool" (cpupool0), and once for an actually in-use pool.
(Juergen, can you correct me if I'm wrong?)  Is it possible that
that's the difference in the pointers that you're seeing?
