Considering that halt() is e.g. called (in an endless loop) from smp_send_stop() on all but the current CPU, wouldn''t it make more sense to make this HYPERVISOR_block() rather than just ((void)0)? It would seem to me that HYPERVISOR_block() comes fairly close the what the hlt instruction means on real hardware.
