I'm assuming that Martin will eventually queue this up. But probably
for 4.17, then we can always flag it for a backport to stable once
it's been thoroughly tested.

Jens, thanks for reply.

I wonder if folks agree that in this case we should revert 

84676c1f21e8 genirq/affinity: assign vectors to all possible CPUs

for v4.16.

Even 84676c1f21e8 is reverted, IO failure or hang can still be triggered
easily when doing CPU online/offline test.

So this patchset is really needed.

Thanks,
Ming
