The entry points that we are concerned about are:
ppc_cpu_get_phys_page_debug
ppc_cpu_tlb_fill
Currently there is a hook, pcc->handle_mmu_fault, which is used by
ppc_cpu_tlb_fill, but is insufficiently general. We're going to remove that hook.
We're going to add a new hook with the same interface as ppc_radix64_xlate that
will be used by both ppc_cpu_get_phys_page_debug and ppc_cpu_tlb_fill.

Only ppc_cpu_tlb_fill should call tlb_set_page.
