Oh, I was looking at the wrong branches. Sigh.

Yeah, we just do an unlocked "se->vruntime -= old->min_vruntime -
new->min_vruntime;" in migrate, and remove/add it in

This still isn't replacing min_vruntime with anything cool, perhaps you
and Andrew were using opposite definitions of relative here - we have
fair tasks always having a vruntime that is relative to min_vruntime,
rather than temporarily having the 0-based one when doing
