Let's finally add s390 support for virtio-mem; my last RFC was sent
4 years ago, and a lot changed in the meantime.
The latest QEMU series is available at [1], which contains some more
details and a usage example on s390 (last patch).
There is not too much in here: The biggest part is querying a new diag(500)
STORAGE_LIMIT hypercall to obtain the proper "max_physmem_end".

I'll apply the whole series as soon as there are ACKs for the third
patch, and from the KVM guys for the whole series.
Christian, Janosch, Claudio?
Acked-by: Christian Borntraeger <borntraeger@xxxxxxxxxxxxx>
for the series.
@Eric Farman,
Was someone from your team planning to look into this (testing, review whatever)?
