	  Twofish cipher algorithm (x86_64, 3-way parallel).

	  Twofish was submitted as an AES (Advanced Encryption Standard)
	  candidate cipher by researchers at CounterPane Systems.  It is a
	  16 round block cipher supporting key sizes of 128, 192, and 256
	  bits.

	  This module provides Twofish cipher algorithm that processes three
	  blocks parallel, utilizing resources of out-of-order CPUs better.
