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=1.
Also improve error logging by adding the CPU number.

I think we should send this one to stable also.
Fixes: eac1e731b59e ("powerpc/xive: guest exploitation of the XIVE interrupt controller")
yes.
Cc: stable@vger.kernel.org # v4.14+
yes. I just added the Cc:. I am not sure that will work with patchwork though.
They don't accept patches that way.
I'll add the tags and commit it.
cheers
