With the performance fix for the generic code, it may no longer be worthwhile to have a special arm64 implementation as well. I will respin a series containing everything I think is needed. The SM3 patch is independent, and is good to go IMO (with Steve's Tested-by) Thanks, Ard.
Add an implementation of SHA3 to arm64 using the new special instructions, and another one using scalar instructions but coded in assembler (#2) In preparation of that, fix a bug in the SHA3 (#1) and add some new test vectors to get better test coverage (#3). v2: Drop generic SHA3 as a fallback for the arm64 module. Instead, provide a special arm64 version to use as a fallback when the instructions are not available or when executing in a context that does not allow SIMD Drop patches that simplify the generic SHA3 and make it reusable by other modules.
