In order to make the tree bisectable, combine bug fixes into the changes
that add the bugs instead of letting them live in the final tree when
they don't need to.

You should have just combined this patch into the patch that added the
FCS inversion stuff.

You're going to need to respin and repost this entire patch set after
fixing all of these problems I've found.

Thanks.
