Come on! We need it just to iterate over a list of available
livepatches. The logic used to manage this list is trivial.
klp_force_transition() itself is more complicated and it
logically fits into transitions.c.

I do not want to fight over this. If you resist, I'll move it.
I just wanted to share my view.
