OK, so I was looking at the right tree. Then I don't understand how 
SHUTDOWN_soft_reset would be reached for a non-privileged domain. The 
only path that I see is

     domain_shutdown()
     {
         ...
         if ( is_hardware_domain(d) )
             hwdom_shutdown(reason);
         ...
     }

Is there another path to handle this op?

Thanks.
