If you look at a modern linux distro, nothing should need/use iopl and co anymore, so maybe an interesting question is if we can stick these behind a CONFIG_ option (default on of course for compatibility)... just like some of the /dev/mem like things are now hidable for folks who know they don't need them. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
