Actually then you can take the xc_cpuid_x86 function pretty much unmodified
(of course regs[0-3] become eax-edx, and input[1] is not needed).

The other stuff in the asm code is to ensure that cpuid traps into the
hypervisor when run in a pv guest. If you don't need to run in a pv guest
then you don't need that extra code.
