From 3d387ef08c40382315b8e9baa4bc9a07f7c49fce Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Sat, 8 Jun 2013 12:17:42 +0300 Subject: Revert "crypto: blowfish - add AVX2/x86_64 implementation of blowfish cipher" This reverts commit 604880107010a1e5794552d184cd5471ea31b973. Instruction (vpgatherdd) that this implementation relied on turned out to be slow performer on real hardware (i5-4570). The previous 4-way blowfish implementation is therefore faster and this implementation should be removed.
