Cover letter [PATCH v3 0/4] crypto: aegis128 enhancements

This series supersedes [0] '[PATCH] crypto: aegis128/neon - optimize tail block handling', which is included as patch #3 here, but hasn't been modified substantially.

Patch #1 should probably go to -stable, even though aegis128 does not appear to be widely used.

Patches #2 and #3 improve the SIMD code paths.

Patch #4 enables fuzz testing for the SIMD code by registering the generic code as a separate driver if the SIMD code path is enabled.

Changes since v2:
- add Ondrej's ack to #1
- fix an issue spotted by Ondrej in #4 where the generic code path would still use some of the SIMD helpers
