The argument order need to be swapped, second argument should be 
'fault_address' and third 'error_code'

         return kvm_mmu_page_fault(&svm->vcpu, fault_address, error_code,
                          svm->vmcb->control.insn_bytes,
                          svm->vmcb->control.insn_len);


With that fixed.
