Are the changes specific to x86, right? boot_cpu_has() seems x86 only, and kvm_para_*() isn't provided for all architectures.

The best would be to provide a standard API for such detection. But, as a workaround, we may need a simple ifdef.

Is this really needed ? This is driver for controllers which is used only (AFIK) with x86 and x86_64 CPUs.

I remember vaguely the implementation on PPC and others. Who knows. (And you can run a kernel in VM, right? :)
