If it returns EINVAL we just ignore the register.

I wonder if it's the right thing to do. You remember how you were bitten by less-than-sensible error handling in the x86 kvm_arch_put_registers.

Yeah, I think we'll have to do a flag day as of which we declare PPC as a first class supported citizen. At that point we'll have compat machine types and start to do more intense error checking.
