Herbert Xu 5c98d62059 crypto: aead - Add aead_alg_instance
Now that type-safe init/exit functions exist, they often need
to access the underlying aead_instance.  So this patch adds the
helper aead_alg_instance to access aead_instance from a crypto_aead
object.

Herbert Xu 5eb8ec6dc8 crypto: aead - Add type-safe init/exit functions
As it stands the only non-type safe functions left in the new
AEAD interface are the cra_init/cra_exit functions.  It means
exposing the ugly __crypto_aead_cast to every AEAD implementor.

This patch adds type-safe init/exit functions to AEAD.  Existing
algorithms are unaffected while new implementations can simply
fill in these two instead of cra_init/cra_exit.

Stephan Mueller cf58fcb1be crypto: jitterentropy - remove timekeeping_valid_for_hres
The patch removes the use of timekeeping_valid_for_hres which is now
marked as internal for the time keeping subsystem. The jitterentropy
does not really require this verification as a coarse timer (when
random_get_entropy is absent) is discovered by the initialization test
of jent_entropy_init, which would cause the jitter rng to not load in
that case.

Herbert Xu 19fa77522e crypto: algif_aead - Switch to new AEAD interface
This patch makes use of the new AEAD interface which uses a single
SG list instead of separate lists for the AD and plain text.

Note that the user-space interface now requires both input and
output to be of the same length, and both must include space for
the AD as well as the authentication tag.

Herbert Xu 693b549d39 crypto: aead - Document behaviour of AD in destination buffer
This patch defines the behaviour of AD in the new interface more
clearly.  In particular, it specifies that if the user must copy
the AD to the destination manually when src != dst if they wish
to guarantee that the destination buffer contains a copy of the
AD.

The reason for this is that otherwise every AEAD implementation
would have to perform such a copy when src != dst.  In reality
most users do in-place processing where src == dst so this is
not an issue.

This patch also kills some remaining references to cryptoff.
