4.9-stable review patch. If anyone has any objections, please let me know.

From: Arnd Bergmann arnd@arndb.de
commit 3cd18d1981731d5f74b8e437009124ac99905d14 upstream.
The recent rework introduced a possible randconfig build failure when CONFIG_CRYPTO configured to only allow modules:
security/keys/big_key.o: In function `big_key_crypt': big_key.c:(.text+0x29f): undefined reference to `crypto_aead_setkey' security/keys/big_key.o: In function `big_key_init': big_key.c:(.init.text+0x1a): undefined reference to `crypto_alloc_aead' big_key.c:(.init.text+0x45): undefined reference to `crypto_aead_setauthsize' big_key.c:(.init.text+0x77): undefined reference to `crypto_destroy_tfm' crypto/gcm.o: In function `gcm_hash_crypt_remain_continue': gcm.c:(.text+0x167): undefined reference to `crypto_ahash_finup' crypto/gcm.o: In function `crypto_gcm_exit_tfm': gcm.c:(.text+0x847): undefined reference to `crypto_destroy_tfm'
When we 'select CRYPTO' like the other users, we always get a configuration that builds.
