Subject: [PATCH v11 3/4] crypto: arm64/aes-cts-cbc - factor out CBC en/decryption of a walk
Date: Wed, 14 Aug 2019 19:37:45 +0300	[thread overview]
Message-ID: <20190814163746.3525-4-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20190814163746.3525-1-ard.biesheuvel@linaro.org>

The plain CBC driver and the CTS one share some code that iterates over
a scatterwalk and invokes the CBC asm code to do the processing. The
upcoming ESSIV/CBC mode will clone that pattern for the third time, so
let's factor it out first.
