Looks like nommu stuff, as I know assabet builds with my mmu-full configuration.

My guess is that it (and other copypage-* headers) need to include asm/page.h, but maybe this is another nommu problem, I don't know. I don't have time to analyse these as I'm still catching up with email, and will be for a while yet.
