    kernel - Improve SMP collision statistics
    
    * Populate the per-cpu collision counter and label from the spinlock,
      lockmgr lock, and mutex code.  The token code already used it.
    
    * Pass __func__ to the spinlock routines so it can be copied into
      the per-cpu collision label.
