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
