Hey Masahiro,
Your touch might be helpful here. CRYPTO_LIB_CHACHA20POLY1305 is a
tristate and depends on as well as selects other things that are
tristates.
Meanwhile BIG_KEYS is a bool, which needs to select
CRYPTO_LIB_CHACHA20POLY1305. However, it gets antsy if the the symbol
its selecting has =m items in its hierarchy.
Any suggestions? The ideal thing to happen would be that the select of
CRYPTO_LIB_CHACHA20POLY1305 in BIG_KEYS causes all of the descendants
to become =y too.
