I've taken this pull, but I really think the minimal and more
straightforward fix would have been to just make do_fork(),
kernel_thread() and clone() change the flags field from "unsigned
long" to "unsigned int".

I don't see why that wouldn't have fixed things, and it would have
been simpler and more obvious, I think.

Doesn't matter, I guess.
