  80           CTR and XTS modes
  81
  82           Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
  83           and for XTS mode encryption, CBC and XTS mode decryption speedup is
  84           around 25%. (CBC encryption speed is not affected by this driver.)
  85           This implementation does not rely on any lookup tables so it is
  86           believed to be invulnerable to cache timing attacks.
