I think so.  So we'd end up with:

- DEFINE_PER_CPU and kmalloc_percpu() work in core kernel, and use the 32k
  pool.

- DEFINE_PER_CPU in modules uses the 32k pool as well (core kernel does the
  allocation).

- kmalloc_per_cpu() is unavailble to modules (it ain't exported).

AFAICT the only thing which will break is sctp, which needs a trivial
conversion to DEFINE_PER_CPU.
