Con Kolivas 3b0bd9bc6f [PATCH] sched: smp nice bias busy queues on idle rebalance 
To intensify the 'nice' support across physical cpus on SMP we can bias the
loads on idle rebalancing. To prevent idle rebalance from trying to pull tasks
from queues that appear heavily loaded we only bias the load if there is more
than one task running.

Add some minor micro-optimisations and have only one return from __source_load
and __target_load functions.

Fix the fact that target_load was not biased by priority when type == 0.
