Subject: [PATCH 06/10] crypto: arm64/chacha20 - remove cra_alignmask
Date: Tue, 17 Jan 2017 15:22:33 +0000 [thread overview]
Message-ID: <1484666557-31458-7-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1484666557-31458-1-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.
