ca7c39385c [CRYPTO] api: Handle unaligned keys in setkey
setkey() in {cipher,blkcipher,ablkcipher,hash}.c does not respect the
requested alignment by the algorithm. This patch fixes it. The extra
memory is allocated by kmalloc() with GFP_ATOMIC flag.

03f5d8cedb [CRYPTO] api: Proc functions should be marked as unused
The proc functions were incorrectly marked as used rather than unused.
They may be unused if proc is disabled.

27d2a33007 [CRYPTO] api: Allow multiple frontends per backend
This patch adds support for multiple frontend types for each backend
algorithm by passing the type and mask through to the backend type
init function.

055bcee310 [CRYPTO] digest: Added user API for new hash type
The existing digest user interface is inadequate for support asynchronous
operations.  For one it doesn't return a value to indicate success or
failure, nor does it take a per-operation descriptor which is essential
for the issuing of requests while other requests are still outstanding.

This patch is the first in a series of steps to remodel the interface
for asynchronous operations.

For the ease of transition the new interface will be known as "hash"
while the old one will remain as "digest".

This patch also changes sg_next to allow chaining.
