Subject: [PATCH v2 16/20] crypto: mark NEON bit sliced AES helper ciphers
Date: Fri, 27 Mar 2015 23:59:18 +0100 [thread overview]
Message-ID: <2775612.Q05lyYA2td@tachyon.chronox.de> (raw)
In-Reply-To: <1746748.uPZFXamDiM@tachyon.chronox.de>
Flag all NEON bit sliced AES helper ciphers as internal ciphers to
prevent them from being called by normal users.
Signed-off-by: Stephan Mueller <smueller@chronox.de>
