[PATCH] do_fork updates for ppc

[Christoph Hellwig]

Update ppc for mingo's do_fork changes.  Together with the pmac compile
fixes this allows me to stay at the bledding edge with my my ibook..

Paul, any chance for sending Linus more updates from the linuxppc tree?
I still can't build SMP or the sound drivers in mainline..
