Adding these patches would be ok but not strictly necessary as upstream does not
enable mepoch extension for the 3.1 machine.
If you decide to pick those nevertheless, then you could also pick
commit f2a7d157711 ("s390x/cpumodel: add z14 GA2 model")
But as I said. I think those are not strictly necessary.

Yes.
In addition to that there are 2 (or optional 3) bugfixes on top that would be important to have in bionic,disco (and also eaon).
mandatory:
https:/
(s390x/cpumodel: also change name of vxbeh)
https:/
( s390x/cpumodel: remove esort from the default model)
optional:
https:/
( s390x/cpumodel: change internal name of vxpdeh to match description )
I expect Cornelia to send a pull request soon so I hope to have final commit IDs soon.
