Hi,
This two patches support physical CPU hotplug, so that we can make blk-mq
scale well when new physical CPU is added or removed, and this use case
is normal for VM world.
Also this patchset fixes the following warning reported by Christian
Borntraeger:

Christoph Hellwig (2):
genirq/affinity: assign vectors to all possible CPUs
blk-mq: simplify queue mapping & schedule with each possisble CPU
