Subject: [PATCH 1/6] s390x/cpumodel: add 3931 and 3932

RH-Author: Cornelia Huck <cohuck@redhat.com>

RH-MergeRequest: 21: s390x/cpumodel: add 3931 and 3932

RH-Commit: [1/1] b678fdf9364407c615678980330e496676e04f9e (cohuck/qemu-kvm-c9s)

RH-Bugzilla: 1932191

This defines 5 new facilities and the new 3931 and 3932 machines.

As before the name is not yet known and we do use gen16a and gen16b.

The new features are part of the full model.

The default model is still empty (same as z15) and will be added

in a separate patch at a later point in time.

Also add the dependencies of new facilities and as a fix for z15 add

a dependency from S390_FEAT_VECTOR_PACKED_DECIMAL_ENH to

S390_VECTOR_PACKED_DECIMAL.
