If we want a constant here then we would better define a global one and 
use it throughout the kernel.

Something like

#define LOCAL_NODE (-1)

Maybe in include/*/topology.h ?

This is not really local in the sense of node local but its processor 
local. The speciality here is that we allocate from the per processor
list of objects. cache_alloc_cpu?

The rest looks fine on first glance.
