I'll be amazed if someone complains.
We'll still boot fine on those CPUs without that support code too,
we just won't advertise cx8 to userspace, and /proc/cpuinfo
won't prettyprint the name. whoopdy-do.

Should we actually find someone who a) has one and b) is crazy enough
to still run it today, we could always add this stuff back.
