Doesn't CONFIG_CRYPTO_STATS also need to depend on CONFIG_CRYPTO_USER?
Currently you can enable it but without CRYPTO_USER the API won't be available.
config CRYPTO_STATS
bool "Crypto usage statistics for User-space"
should be:
config CRYPTO_STATS
bool "Crypto usage statistics for User-space"
depends on CRYPTO_USER

This is a long ifdef, so use:
#endif /* CONFIG_CRYPTO_STATS */
