cputest: Add data for Intel(R) Xeon(R) CPU E5-2623 v4 The CPU contains the updated microcode for CVE-2017-5715. The -guest.xml and -json.xml CPU definitions use Skylake-Client CPU model rather than Broadwell. This is similar to Xeon-E5-2650-v4 and it is caused by our CPU model selection code when no model matches the CPU signature (family + model). We'd need to maintain a complete list of CPU signatures for our CPU models to fix this.

cpu: Add Skylake-Client-IBRS CPU model This is a variant of Skylake-Client with indirect branch prediction protection. The only difference between Skylake-Client and Skylake-Client-IBRS is the added "spec-ctrl" feature.
