The leaf at 0x7 is special because in addition to putting 0x7 it also lets you put a value into ECX to get a particular feature subleaf. In this case we want ECX=0x0, and any processor which supports EAX=0x7 (which we do check) supports ECX=0x0.

This provides flags into more modern features on Intel CPUs, including some which most of our machines definitely do not have. If you use any of these features, check to make sure they're supported.
