  SVN rev 220362 on 2011-04-05 14:15:58Z by attilio
  
  Extend the DDB command "watchdog" with the ability to specify a timeout
  value.
  
  The timeout is expressed in the form T(N) = (2^N * nanoseconds) and can
  be easilly extracted from the watchdog interface as a WD_TO_* macro.
  That new functionality is supposed to fix re-entering the kernel from DDB
  re-enabling the watchdog again (previously disabled) and also offer the
  possibility to break for deadlocked DDB commands.
  
  Please note that retro-compatibility is retained.
