Why are we stuffing this into mmu.h? mmu.h is not the header file for
arch/arm/mm/mmu.c - although they have the same base filename, they are
not really related.
asm/mmu.h is supposed to be a kernel-wide include file for the mm_context_t
thing, and should not be filled with arch-private stuff.
Please find a better location for this.
