My argument has always been that drivers should do the emulation of 64-bit accesses when there is no native support. IO registers tend to have side effects when read/written. How do we know whether the low-half or the high-half should be written first? This isn't something that an architecture can really dictate. What may be right for one hardware device may not be correct for another. -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
