Yeah, I have the static_cpu_has() simplification patchset v2 ready, will
send out tomorrow.

And yeah, as a next step, we probably should think about hiding
boot_cpu_has() and using solely static_cpu_has() everywhere instead.

The cpu_has() thing takes struct cpuinfo_x86 * and I'll bet a bunch of
money that a lot of the callsites could do static_cpu_has(), i.e., look
at boot CPU bits instead. That's for later, though.
