Merge branch 'ibmvnic-affinity-hints'

Nick Child says:

====================
ibmvnic: Introduce affinity hint support

This is a patchset to do 3 things to improve ibmvnic performance:
    1. Assign affinity hints to ibmvnic queue irq's
    2. Update affinity hints on cpu hotplug events
    3. Introduce transmit packet steering (XPS)

NOTE: If irqbalance is running, you need to stop it from overriding
  our affinity hints. To do this you can do one of:
   - systemctl stop irqbalance
   - ban the ibmvnic module irqs
      - you must have the latest irqbalance v9.2, the banmod argument was broken before this
      - in /etc/sysconfig/irqbalance -> IRQBALANCE_ARGS="--banmod=ibmvnic"
      - systemctl restart irqbalance
====================
