target/s390x: move @deprecated-props to CpuModelExpansion Info
CpuModelInfo is used both as command argument and in command returns. Its @deprecated-props array does not make any sense in arguments, and is silently ignored. We actually want it only as return value of query-cpu-model-expansion. Move it from CpuModelInfo to CpuModelExpansionType, and document its dependence on expansion type property. This was identified late during review [1] and we have to fix it up while it's not part of an official QEMU release yet. [1] https://lore.kernel.org/qemu-devel/20240719181741.35146-1-walling@linux.ibm.com/ Message-ID: <20240726203646.20279-1-walling@linux.ibm.com> Fixes: eed0e8ffa38f ("target/s390x: filter deprecated properties based on model expansion type") Signed-off-by: Collin Walling <walling@linux.ibm.com> [ david: - add "Fixes", adjust description, reference v3 instead - make property s390x-only and non-optional - fixup "populate" vs. "populated" ] Signed-off-by: David Hildenbrand <david@redhat.com>
