BOOKE KVM calling load_up_fpu from C?

[Michael Neuling]

Scott,

I was looking at changing how load_up_fpu works and I found this in
arch/powerpc/kvm/booke.h:

static inline void kvmppc_load_guest_fp(struct kvm_vcpu *vcpu)
{
#ifdef CONFIG_PPC_FPU
	if (vcpu->fpu_active && !(current->thread.regs->msr & MSR_FP)) {
		load_up_fpu();
		current->thread.regs->msr |= MSR_FP;
	}
#endif
}

I'm wondering how this is suppose to work since load_up_fpu is suppose
to have MSR in R12?
