+From 61cc715240d2d3f9511ca88043a3e9797c11482f Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Define AESNI_ASM if AESNI assembler is included, and use it
+
+Because we have cases where basic assembler support isn't present, but
+AESNI asssembler support is, we need a separate macro that indicates
+that, and use it.
