157 	  On ARM processors without the Crypto Extensions, this is the
158 	  fastest AES implementation for single blocks.  For multiple
159 	  blocks, the NEON bit-sliced implementation is usually faster.
160 
161 	  This implementation may be vulnerable to cache timing attacks,
162 	  since it uses lookup tables.  However, as countermeasures it
163 	  disables IRQs and preloads the tables; it is hoped this makes
164 	  such attacks very difficult.
