Nick Piggin a3f21bce1f [PATCH] sched: tweak affine wakeups
Do less affine wakeups.  We're trying to reduce dbt2-pgsql idle time
regressions here...  make sure we don't don't move tasks the wrong way in an
imbalance condition.  Also, remove the cache coldness requirement from the
calculation - this seems to induce sharp cutoff points where behaviour will
suddenly change on some workloads if the load creeps slightly over or under
some point.  It is good for periodic balancing because in that case have
otherwise have no other context to determine what task to move.

But also make a minor tweak to "wake balancing" - the imbalance tolerance is
now set at half the domain's imbalance, so we get the opportunity to do wake
balancing before the more random periodic rebalancing gets preformed.
