Looking into supporting virtio-mem
a) without a shared zeropage for the memory backing of the device --
    not allowing the driver to read unplugged memory
b) on architectures with memory properties for RAM (e.g., s390x with
    storage keys and storage attributes)
requires extension of the spec to handle both cases cleanly and describe
the expected semantics.

I'll open a github issue soon; in the meantime, I'll work on the actual
implementation in QEMU and Linux.

LGTM, but would like a second opinion.

Thanks Conny! I'll wait for more feedback before I open a github issue / 
request a vote.
