Subject: [PATCH v2 04/10] crypto: arm64/aes-ce-ccm - remove cra_alignmask
Date: Mon, 23 Jan 2017 14:05:20 +0000	[thread overview]
Message-ID: <1485180326-25612-5-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1485180326-25612-1-git-send-email-ard.biesheuvel@linaro.org>

Remove the unnecessary alignmask: it is much more efficient to deal with
the misalignment in the core algorithm than relying on the crypto API to
copy the data to a suitably aligned buffer.
