I think the cpu_alloc branch itself is fine because it only contains the
allocator and a single use case. The only point of disagreement at this
point is the uppercase / lowercase use. Currently its a separate API (its
not replacing allocpercpu) and therefore easy to merge.

The more invasive stuff is stage2 and the following which is not in next
yet. The way I envision to go forward is with a gradual transition to the
new APIs converting dynamic percpu users to use the new percpu operations
and functionality.

The whole thing becomes riskier if we directly replace all allocpercpu
users as proposed by Rusty.

Rusty, are you going to take this on?
