As soon as one does that one can also save a lot of computational overhead by using 32bit instead of 64bit. The question is then how easy that is possible. bye, Roman - 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/
