Subject: [PATCH v2 11/11] wireguard: Kconfig: select CRYPTO_BLAKE2S_ARM

From: Eric Biggers <[email protected]>

When available, select the new implementation of BLAKE2s for 32-bit ARM.
This is faster than the generic C implementation.

When this series is ready, feel free to pull this commit in via
Herbert's tree, rather than my usual wireguard-linux.git->net-next.git
route. That will ensure the blake2s stuff lands all at once and we
won't have to synchronize anything.
