Implement support for the hypervisor diagnose 0x26c ('Access Certain System Information'). It passes a request buffer and a subfunction code, and receives a response buffer and a return code. Also add the scaffolding for the 'MAC Services' subfunction. It may be used by network devices to obtain a hypervisor-managed MAC address.
