Hmm, ok, I've re-acquainted myself with it. And I have to admit that I
can't see anything wrong. The whole "update_wall_clock" and the shadow
timekeeping state is confusing as hell, but seems fine. We'd have to
avoid update_wall_clock for a *long* time for overflows to occur.
And the overflow in 32 bits isn't that special, since the only thing
that really matters is the overflow of "cycle_now - tkr->cycle_last"
within the mask.
So I'm not seeing anything even halfway suspicious.
