     72 	  On ARM processors without the Crypto Extensions, this is the
     73 	  fastest AES implementation for single blocks.  For multiple
     74 	  blocks, the NEON bit-sliced implementation is usually faster.
     75 
     76 	  This implementation may be vulnerable to cache timing attacks,
     77 	  since it uses lookup tables.  However, as countermeasures it
     78 	  disables IRQs and preloads the tables; it is hoped this makes
     79 	  such attacks very difficult.

     93 	  around 25%. (CBC encryption speed is not affected by this driver.)
