Subject: [PATCH 09/16] crypto: mark Serpent AVX2 helper ciphers
Date: Thu, 19 Mar 2015 08:02:39 +0100	[thread overview]
Message-ID: <7972950.f9f3JLREoG@tachyon.chronox.de> (raw)
In-Reply-To: <21952258.n2qYaab1Is@tachyon.chronox.de>

Flag all Serpent AVX2 helper ciphers as internal ciphers to prevent
them from being called by normal users.
