Tangential, but I've often wondered what are the upsides of keeping
CONFIG_CRYPTO_ALGAPI as a separate config option in the first place? Every
single item in crypto/ ends up "select"ing it (directly or transitively)
so it makes all sense to just do away with it and keep it == CONFIG_CRYPTO
in the Makefile, thusly:
[PATCH] crypto: Remove CONFIG_CRYPTO_ALGAPI config option
Because all other options in crypto/ end up selecting it anyway. So let's
make it a default part of the rest of "core" crypto stuff, that gets built
whenever CONFIG_CRYPTO == y.
