  Modified files:
    sys/bus/cam          cam_sim.c cam_sim.h cam_xpt.c 
  Log:
  Fix an issue where CAM would attempt to illegally get a lockmgr() lock
  from an interrupt via xpt_done().  Use a spin lock instead.
  
  Fix an issue where camisr_runqueue() was not protecting sim->sim_doneq
  which could then race against an interrupt via xpt_done() and corrupt
  the list.
