AFAICS, pte_pgprot is only defined on three architectures that have the config symbol above set. It shouldn't compile on the others. I have a patch that factors out follow_pte and builds follow_pfn and follow_phys on top of that. I can send it monday, no access to it from here right now. Then we can keep follow_phys private to this configuration.
