[Xen-devel] halt() and safe_halt()
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.
Thanks, Jan
