This v2 is a follow-up to both 'crypto: aegis128 - add NEON intrinsics version for ARM/arm64' [0] and 'crypto: morus - remove generic and x86 implementations' [1]. Since there is some overlap, it makes sense to merge them and avoid merge conflicts. Now that aegis128 has been announced as one of the winners of the CAESAR competition, it's time to provide some better support for it on arm64 (and 32-bit ARM *) This time, instead of cloning the generic driver twice and rewriting half of it in arm64 and ARM assembly, add hooks for an accelerated SIMD path to the generic driver, and populate it with a C version using NEON intrinsics that can be built for both ARM and arm64. This results in a speedup of ~11x, resulting in a performance of 2.2 cycles per byte on Cortex-A53. Patches #3 and #4 are fixes/improvements for the generic code. Patch #5 adds the plumbing for using a SIMD accelerated implementation. Patch #6 adds the ARM and arm64 code, and patch #7 adds a speed test. Since aegis128l and aegis256 were not selected, and nor where any of the morus contestants (which are in fact found to be cryptographically broken), patches #1 and #2 remove these entirely. Changes since v1s: - add reference to research paper (#1) - drop hunks against m68k defconfigs - these get regenerated automatically anyway, and so it is better to avoid the potential merge conflicts. - drop patch to use unaligned accessors where it isn't needed - drop hunks against aegis variants that are being removed (#3) - add acks from Ondrej * 32-bit ARM today rarely provides the special AES instruction that the implementation in this series relies on, but this may change in the future, and the NEON intrinsics code can be compiled for both ISAs.
