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.

Together they can be used to access encrypted images
created with loop-AES.

Loop-AES v2.x multi-key-v2 mode corresponds to the
dm-crypt cipher spec "aes-lmk2-plain64-multi:64", v2.x
corresponds to "aes-lmk3-plain64-multi:64".

Tested on mips32 and x86_64. 

To actually use this with Loop-AES encrypted images
you will need a key derivator which converts Loop-AES
format keyfiles into a hexstring for dm-crypt.

I'm putting some rough code for testing up on 
http://hinterhof.net/~max/keyderive-0.1.tar.gz

Please note that this is not intended to be used with
any valuable keys yet. I'll work on a robust derivator
once the kernel side is done.

Looking forward to comments and review,

	Max
