Add irq_spread() function that makes the driver working 15% faster than
with cpumask_local_spread()

Yury Norov (3):
  cpumask: add cpumask_weight_andnot()
  cpumask: define cleanup function for cpumasks
  net: mana: add a function to spread IRQs per CPUs

Process would be to tag this for which tree it aims for. Since this
looks like an improvement and includes cleanup and changes to add a new
helper function that makes me think it would be net-next.

Thanks,
