Hi Peter,

the "max" cpu in x86 and s390 is a class,

and then "host" has "max" as parent.

This would be a convenient setup for ARM too, as it would allow to put common 
code between kvm and tcg in the "max" class,
and allow "host" to specialize the behavior for KVM (and in the future HVF 
probably).

Would changing the class hierarchy this way be acceptable, cause any problems?

I ask specifically because on the x86 side I had to limit my changes to the 
hierarchy to adding objects,
but I would not change the relationship between them.

Thanks,

Claudio
