  Modified files:
    sys/kern             bus_if.m subr_bus.c 
  Log:
  Add a default method for BUS_ADD_CHILD() that just calls
  device_add_child_ordered().  Previously, a device driver that wanted to
  add a new child device in its identify routine had to know if the parent
  driver had a custom bus_add_child method and use BUS_ADD_CHILD() in that
  case, otherwise use device_add_child().  Getting it wrong in either
  direction would result in panics or failure to add the child device.  Now,
  BUS_ADD_CHILD() always works isolating child drivers from having to know
  intimate details about the parent driver.
