Yeah, I think we're down in the noise really here. Some older
versions of the Linux kernel incorrectly emitted a WFI insn
rather than the cp15 op, but that bug was fixed. In any case
I doubt anybody's written code that relies on the wfi insn
being implemented as a nop...

Calling it a v6k in qemu is probably on balance better than not.
