    kernel - Disable swapcache once paniced or if dumping
    
    * Make sure we do not attempt to read or write via the swapcache if the
      machine is paniced or has been dumped via the debugger.  This avoids
      corrupting the dump and avoids corrupting reads shortcut through the
      swapcache under these conditions.
