crap. Modules deal with per-device and per-mount objects. If a module
cannot use kmalloc_per_cpu on behalf of the primary object which it manages
then the facility is simply not useful to modules.

Ok then.

Please address the ia64 concerns then :-) It probably means we
have to stay with the dereferencing stuff... at which point you
might as well use normal kmalloc() and smp_processor_id() indexing
inside of modules.
