So what was the reasoning about CPUID bits being so expensive so that we
need to match models? Ditto for the splitlock situation - that thing is
supported on a bunch of models but nope, not a CPUID bit in sight. What
was the convincing argument that made hw folks give a CPUID bit to the
PPIN thing? Perhaps we could use it there too. :)
