[PATCH] hw: add compat machines for 5.0

[PATCH] hw: add compat machines for 5.0

[Cornelia Huck]

Add 5.0 machine types for arm/i440fx/q35/s390x/spapr.

For i440fx and q35, unversioned cpu models are still translated
to -v1; I'll leave changing this (if desired) to the respective
maintainers.

Signed-off-by: Cornelia Huck <cohuck@redhat.com>

also pushed out to https://github.com/cohuck/qemu machine-5.0

x86 folks: if you want to change the cpu model versioning, I
can do it in this patch, or just do it on top yourselves

Thanks for taking care of this, Cornelia!

The plan is to eventually set
default_cpu_version=CPU_VERSION_LATEST, but we won't change
default_cpu_version in QEMU 5.0 yet.

We need to keep default_cpu_version=1 for a few releases, until
management software adapts.  See the "Runnability guarantee of
CPU models" section at qemu-deprecated.texi.

So, do we have a final verdict yet (keep it at v1)?

If yes, I'll queue this via the s390 tree, unless someone else beats me
to it.

We won't change default_cpu_version in 5.0, so:
