[PULL,01/17] s390x/cpumodel: add 3931 and 3932

Commit Message

Cornelia Huck July 8, 2021, 3:18 p.m. UTC

From: Christian Borntraeger <[e-mail]>

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.
