  Modified files:
    sys/kern             kern_switch.c 
    sys/sys              ktr.h 
  Log:
  Add basic critical section tracing to KTR using event type KTR_CRITICAL.
  This generates a KTR event for each critical section entered and exited.
  
  It would be desirable to also log the filename and line number of the
  source entering or exiting the critical section, but this requires
  hacking up the critical section API, so I've not done that yet.
