Con Kolivas 6dd4a85bb3 [PATCH] sched: correct smp_nice_bias ...

The priority biasing was off by mutliplying the total load by the total
priority bias and this ruins the ratio of loads between runqueues. This
patch should correct the ratios of loads between runqueues to be proportional
to overall load. -2nd attempt.

From: Dave Kleikamp <shaggy@austin.ibm.com>

  This patch fixes a divide-by-zero error that I hit on a two-way i386
  machine.  rq->nr_running is tested to be non-zero, but may change by the
  time it is used in the division.  Saving the value to a local variable
  ensures that the same value that is checked is used in the division.
