Jason A. Donenfeld d540725871 kernel-5.4: backport fd16931a2f51 for chacha neon 
Without this patch, the chacha block counter is not incremented on neon
rounds, resulting in incorrect calculations and corrupt packets.

This also switches to using `--no-numbered --zero-commit` so that future
diffs are smaller.

Subject: [PATCH] crypto: testmgr - add test cases for Blake2s
commit 17e1df67023a5c9ccaeb5de8bf5b88f63127ecf7 upstream.
As suggested by Eric for the Blake2b implementation contributed by
David, introduce a set of test vectors for Blake2s covering different
digest and key sizes.
blake2s-128 blake2s-160 blake2s-224 blake2s-256
