Merged patches 1-4. I agree with Jani that changing jump labels is a pure
bikeshed, so didn't apply them.

Also I'll repeat that imo checkpatch patches are great to get started, but
it's much better to do more involved work. Both since that tends to be
more interesting, and fixing all the checkpatch issues will rob the next
newbies of some great starting opportunity. Which means from now on I'll
only selectively apply your checkpatch patches.

We have todo list with some ideas at:
