Subject: [PATCH 8/8] crypto: safexcel - reduce alignment of stack buffer
Date: Wed, 6 Apr 2022 16:27:15 +0200 [thread overview]
Message-ID: <20220406142715.2270256-9-ardb@kernel.org> (raw)
In-Reply-To: <20220406142715.2270256-1-ardb@kernel.org>
Now that skcipher, AEAD and ahash have all been updated to use a request
structure that itself is not aligned for DMA, we can relax the alignment
requirement of the EIP197 stack buffers as well.
