For reference, this is the delta from SandyBridge:
model = 58;
stepping = 9;
features[FEAT_1_ECX] |=
CPUID_EXT_F16C | CPUID_EXT_RDRAND;
features[FEAT_7_0_EBX] |=
CPUID_7_0_EBX_FSGSBASE | CPUID_7_0_EBX_SMEP |
CPUID_7_0_EBX_ERMS;
This matches what I see in a real CPU with family/model/stepping IDs
6/58/9.
