[PATCH] hw/s390x/s390-virtio-ccw: Remove the deprecated 4.1 machine type

Posted by Thomas Huth 7 months ago

From: Thomas Huth <thuth@redhat.com>

With the upcoming release of QEMU 10.1, the s390-ccw-virtio-4.1 machine
will be older than 6 years, so according to our machine support policy,
it can be removed now. The V4_1 CPU feature group gets merged into the
minimum CPU feature group now.

Signed-off-by: Thomas Huth <thuth@redhat.com>

 (I forgot to include the 4.1 in my earlier machine clean-up series
  since Daniel's commit f59ee044067a was not merged yet)
