The additional pmd_pgprot implementations only are necessary if we want
to preserve the PROT_NONE protections across a split but that somewhat
forces that PROT_NONE be used as the protection bit across all
architectures. Is that possible? I think I would prefer that
prot-protection-across-splits just went away until it was proven
necessary and potentially recoded in terms of _PAGE_NUMA and friends
instead.
