What is in the definition of a CPU model?  I would expect stuff like:

1) converting CPUID leaf (eax+ecx)/register/bit from and to a string

2) converting MSR bit from and to a string

3) dependencies between CPUID leaves and from CPUID leaves to MSRs

4) XSAVE area offsets

5) dependencies between CPUID leaves and XSAVE areas

Anything else?
