  Modified files:
    sys/kern             kern_mutex.c kern_rwlock.c kern_sx.c 
  Log:
  Adjust td_locks for non-spin mutexes, rwlocks, and sx locks so that it is
  a count of all non-spin locks, not just lockmgr locks.  This can give us a
  much cheaper way to see if we have any locks held (such as when returning
  to userland via userret()) without requiring WITNESS.
