Ok, this one looks pretty good. I like the statics, and I like how it lets
each allocator decide what to do.

Small nit: your mm/slab.c patch does an obviously unnecessary mask in:

cache_alloc_debugcheck_before(cachep, flags & slab_gfp_flags);

but that's stupid, because the bits were already masked earlier.
