Firstly, isn't a probe already a test?

Secondly, there's more HSW models:

case 60: /* 22nm Haswell Core */
case 63: /* 22nm Haswell Server */
case 69: /* 22nm Haswell ULT */
case 70: /* 22nm Haswell + GT3e (Intel Iris Pro graphics) */

Is this really only HSW server, or should they all be listed?
