    sys/kern             subr_witness.c 
  Log:
  - Enforce an implicit lock order that Giant cannot be locked while holding
    any other non-sleepable lock.  In plain English: Giant comes before all
    other mutexes.
  - Add some extra description to the lock order reversal printf's to indicate
    when a reversal is triggered by a hard-coded implicit rule.
