Re: [PATCH v2] cpu_s390: Implement getVendorForModel for IBM Z

When running "virsh domcapabilities" on a s390x host, all the CPU models show up with vendor='unknown' - which sounds kind of weird since the vendor of these mainframe CPUs is well known: IBM. All CPUs starting with either "z" or "gen" match a real mainframe CPU by IBM, so let's return the string "IBM" for those now. The only remaining ones are now the artifical "qemu" and "max" models from QEMU itself, so it should be OK to get an "unknown" vendor for those two. Thanks to Boris Fiuczynski for helping with the domaincapsdata!
