I am going to assume you know more about the exact details of the intel cpu's
than me, so I am not going comment on the technical details. The code seems
cleaner, so this looks like a good thing to do. Just please try to avoid using
the const_cast if it's no absolutely necessary (and it almost never is).

I don't think the `const_cast` here is a good idea. How about we just make this
functions non-const ?

I remember you #including some header to get the __get_cpuid function. Can that
be removed now?
