modes operate on full 512 byte sectors. They use CBC
with an IV derived from the sector number, the data and (for
lmk3 only) an extra 128-bit IV seed.

So change it to be used only for the latter and put
cipher mode string on the stack.

Introduces a mode for dm-crypt which uses multiple
encryption keys (and thus tfms) alternating based on
the sector number and the number of keys.
This change is needed to support loop-AES compatible
block chaining modes, which use "multi:64".

This patch adds export support to md5. The exported type is
defined by struct md5_state.
This is modeled after the equivalent change to sha1_generic,
except only export is added for now.

This set adds an implementation of the Loop-AES block
encryption modes for dm-crypt.
It consists of two main parts:
(1) blkcipher implementation of the Loop-AES block
chaining modes (lmk2, lmk3)
(2) Support for alternating keys in dm-crypt.
The patches are based on cryptodev-2.6.
