+# of non-interleaved subroutine [for number of input blocks up to 3].
+# This is why it makes no sense to implement 2x subroutine. As soon

+ * Support for Intel AES-NI intruction set
+ *   Author: Huang Ying <ying.huang@intel.com>
+ *
+ * Intel AES-NI is a new set of Single Instruction Multiple Data
+ * (SIMD) instructions that are going to be introduced in the next
+ * generation of Intel processor, as of 2009. These instructions
+ * enable fast and secure data encryption and decryption, using the
+ * Advanced Encryption Standard (AES), defined by FIPS Publication
+ * number 197.  The architecture introduces six instructions that
+ * offer full hardware support for AES. Four of them support high
+ * performance data encryption and decryption, and the other two
+ * instructions support the AES key expansion procedure.
+ *
+ * The white paper can be downloaded from:
+ *   http://softwarecommunity.intel.com/isn/downloads/intelavx/AES-Instructions-Set_WP.pdf
+ *
+ * This file is based on engines/e_padlock.c
