The CPUID instruction takes the value of ECX as an input parameter

This needs to go to upstream qemu. I'd suggest adding a new parameter
rather than making ecx an in/out parameter.
You mean something like
host_cpuid(index, subindex, eax, ebx, ecx, edx);
?
Yes.
I'd expect a loop when we use this...
Why a loop? We'll only return the values true for a particular EAX:ECX
combination. The requestor (kernel) will loop.
The kernel doesn't call host_cpuid(). We preload all possible
combinations of eax and ecx in advance.
