This is a note to let you know that I've just added the patch titled crypto: arm64/aes-ce - really hide slower algos when faster ones are enabled to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: crypto-arm64-aes-ce-really-hide-slower-algos-when-fa.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 9146a0e7c4495a3edf72881ecc080a6048080233 Author: Ard Biesheuvel <ardb@xxxxxxxxxx> Date: Thu Dec 17 19:55:15 2020 +0100 crypto: arm64/aes-ce - really hide slower algos when faster ones are enabled [ Upstream commit 15deb4333cd6d4e1e3216582e4c531ec40a6b060 ] Commit 69b6f2e817e5b ("crypto: arm64/aes-neon - limit exposed routines if faster driver is enabled") intended to hide modes from the plain NEON driver that are also implemented by the faster bit sliced NEON one if both are enabled. However, the defined() CPP function does not detect if the bit sliced NEON driver is enabled as a module. So instead, let's use IS_ENABLED() here.
