    kernel - dm_target_crypt - use CRYPTO_F_BATCH
    
    * Allow crypto requests to be dispatched to multiple crypto support
      threads instead of executing the operation synchronously.
    
    * Greatly improves crypto performance on SMP boxes.  25MB/s -> 80MB/s on
      my quad.
    
    * Currently the ivgen code gets in the way because it must be executed
      synchronously before the data crypto op can be initiated.  Further
      performance improvements are possible.
