crypto: arm64/crct10dif-ce - cleanup and optimizations
The x86, arm, and arm64 asm implementations of crct10dif are very difficult to understand partly because many of the comments, labels, and macros are named incorrectly: the lengths mentioned are usually off by a factor of two from the actual code. Many other things are unnecessarily convoluted as well, e.g. there are many more fold constants than actually needed and some aren't fully reduced. This series therefore cleans up all these implementations to be much more maintainable. I also made some small optimizations where I saw opportunities, resulting in slightly better performance. This patch cleans up the arm64 version. Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
