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. -- Mel Gorman SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
