Yeah we can, kernel had the fixes a while now.
It was a bit complex in this case as we had fix A, fix B and all 4 combinations
thereof.
Thanks Jeff!

Bug description:
[Impact]
* Some newer Power8 derivates fail to work correctly e.g. Power S822LC
(8335-GTB)
* This is a toleration change (no exploitation) for those HW releases
following the SRU policy of "For Long Term Support releases we
regularly want to enable new hardware. Such changes are appropriate
provided that we can ensure not to affect upgrades on existing
hardware."
* Without the Fix that hardware won't run Xenial guests under current
Xenials Qemu version
* The fix lets processors that support it run in PowerISA 2.07
compatibility mode (plus a few no-op changes as backport
dependencies)
[Test Case]
* Run a Xenial Guest in KVM on one of the specific HW revisions being
affected.
[Regression Potential]
* I'd rate the potential to regress low for powerpc and next to
impossible for other architectures, reasons:
* Changes are PPC only, so fallout should be contained to that
* Patches and were created by IBM and in Upstream qemu since 2.6
* The effective change is rather small, only allow to saner cpu model
versions (drop some HW dev trash that was left) and add the new types.
[Other Info]
* Needed for certifying this Hardware for Ubuntu
Upon running the virtualization test from the certification test
suite, the kvm guest test fails with the following error:
kvm_init_vcpu failed: Invalid argument
This same test works on multiple other IBM Power 8 and Openpower
servers. kvm-ok tells us that kvm virtualization is supported. I have
tried with SMT enabled and disabled. I have tried the latest cloud
image as well as previous onces we had saved. I have tried running the
qemu-system-ppc64 command found below manually with the same error.
The full output from the test is as follows:
