cycles. While waiting there I added a lot of the extra ()'s I have, (I have never used LISP to any extent). So I compiled the kernel with -Wall and shut up a lot of "suggest you add ()'s", removed a bunch of unused var's and added a couple of declarations here and there. Having a lap-top is highly recommended. My kernel still runs, yell at me if you kernel breaks.
