This is pretty much synonomous with what is allowed to go into high memory, no? While we're on the subject, for the copy_from_user source, prefetchnta is probably indicated. If user space hasn't caused it to be cached already (admittedly, the common case), we *know* the kernel isn't going to look at that data again. - 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/
