The CPU event notification queues on sPAPR should be configured using
a hardware CPU identifier.

The problem did not show up on the Power Hypervisor because pHyp
supports 8 threads per core which keeps CPU number contiguous. This is
not the case on all sPAPR virtual machines, some use SMT=3D1.

Also improve error logging by adding the CPU number.

 I think we should send this one to stable also.

yes. I just added the Cc:. I am not sure that will work with=20
patchwork though.

They don't accept patches that way.

I'll add the tags and commit it.
