Subject: [PATCH 3/5] crypto: chacha20 - Remove cra_alignmask
Date: Wed, 22 Nov 2017 11:51:37 -0800	[thread overview]
Message-ID: <20171122195139.121269-4-ebiggers3@gmail.com> (raw)
In-Reply-To: <20171122195139.121269-1-ebiggers3@gmail.com>

From: Eric Biggers <ebiggers@google.com>

Now that crypto_chacha20_setkey() and crypto_chacha20_init() use the
unaligned access macros and crypto_xor() also accepts unaligned buffers,
there is no need to have a cra_alignmask set for chacha20-generic.
