I still don't much like the name; how about arch_simd_state ? Also, since we're printing an integer, I still prefer we go print the turbo license level. I know level 1 isn't too interesting atm, but consider future hardware widening the thing again and us growing level 3 or something. Also; you were going to shop around with the other architectures to see what they want/need for this interface. I see nothing on that.
