  Log:
  SVN rev 223531 on 2011-06-25 10:28:16Z by avg
  
  unconditionally stop other cpus when entering kdb in smp system
  
  ... and thus retire debug.kdb.stop_cpus tunable/sysctl.
  The knob was to work around CPU stopping issues, which since have been
  either fixed or greatly reduced.  kdb should really operate in a special
  environment with scheduler stopped and interrupts disabled to provide
  deterministic debugging.
  
  Discussed with: attilio, rwatson
