Eric BiggersandJakub Kicinski cb2e6e86ce crypto: cipher - Remove crypto_clone_cipher() 
Since the only caller of crypto_clone_cipher() was cmac_clone_tfm()
which has been removed, remove crypto_clone_cipher() as well.

Note that no tests need to be removed, as this function had no tests.

Herbert Xu 51d8d6d0f4 crypto: cipher - Add crypto_clone_cipher 
Allow simple ciphers to be cloned, if they don't have a cra_init
function.  This basically rules out those ciphers that require a
fallback.

In future simple ciphers will be eliminated, and replaced with a
linear skcipher interface.  When that happens this restriction will
disappear.

Ard BiesheuvelandHerbert Xu 0eb76ba29d crypto: remove cipher routines from public crypto API 
The cipher routines in the crypto API are mostly intended for templates
implementing skcipher modes generically in software, and shouldn't be
used outside of the crypto subsystem. So move the prototypes and all
related definitions to a new header file under include/crypto/internal.
Also, let's use the new module namespace feature to move the symbol
exports into a new namespace CRYPTO_INTERNAL.
