Subject: [PATCH 0/4 V3 net-next] net: mana: Assigning IRQ affinity on HT cores

This patch set introduces a new helper function irq_setup(),
to optimize IRQ distribution for MANA network devices.
The patch set makes the driver working 15% faster than
with cpumask_local_spread().

Souradeep Chakrabarti (1):
  net: mana: Assigning IRQ affinity on HT cores

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