There is no special consideration for user space. Since all useful memeory is mapped 1-1, guess user space would work as is. Unless iam missing something here.. so yes.. there is no protection with 1-1, but guess its like compatibility mode until the code gets converted over. Keith: cced says some of the user space side also is getting converted over with some driver support possibly. So this is an interim problem until X catches up with it. > > -Andi - 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/
