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: lib/chacha20poly1305 - Add missing function
declaration
commit 06cc2afbbdf9a9e8df3e2f8db724997dd6e1b4ac upstream.
This patch adds a declaration for chacha20poly1305_selftest to
silence a sparse warning.
