Thanks, I've queued this to my s390x-next branch now (since nobody else 
objected, I assume the patch should be fine for everybody).

This is a good idea to add all new compat machines
as a single patch.

I did a similar one with 6.3 by error, I think we should get a script to
do this everytime that we increase the version number O:-)

Later, Juan.

So, this apparently causes some problems with one of the avocado tests:

162-tests/avocado/x86_cpu_model_versions.py:X86CPUModelAliases.test_4_1_alias -> AssertionError: None != 'Cascadelake-Server-v1' : Cascadelake-Server must be an alias of Cascadelake-Server-v1

(full output at https://gitlab.com/qemu-project/qemu/-/jobs/1893456217)

I have looked at the patch again and do not see what might be wrong (has
something changed with the cpu model versioning recently?)

Does anyone else (especially the x86 folks) have an idea?
