    kernel - Reduce size of struct spinlock
    
    * Reduce the size of struct spinlock from 16 to 8 bytes.  The description
      field was not being used (we use __func__ instead).  This reduces
      structural bloat for a number of important structures, in particular
      reducing sizeof(struct vm_page) from 136 to 128 bytes.
