[Qemu-devel] [PATCH v1 0/2] s390x cpu model improvements for KVM

We should properly forward the CPUID format bit. CPU model
detection on systems without IBC might select a model with a wrong
CPU type (esp. selecting the business class (BC) model on an enterprise
class (EC) machine). So let's improve that, too.

I am also preparing a patch to properly indicate the correct cpu type
to the guest via STORE CPU ID and STORE HYPERVISOR INFORMATION for the
TCG case, but will send that separately after I tested it (want to write a
kvm-unit-test for STORE CPU ID).

  s390x/cpumodel: improve defintion search without an IBC
