e90b1a2be6 [CRYPTO] aes: Add wrappers for assembly routines
The wrapper routines are required when asmlinkage differs from the usual
calling convention.  So we need to have them.  However, by rearranging
the parameters, they will get optimised away to a single jump for most
people.

6c2bb98bc3 [CRYPTO] all: Pass tfm instead of ctx to algorithms
Up until now algorithms have been happy to get a context pointer since
they know everything that's in the tfm already (e.g., alignment, block
size).

However, once we have parameterised algorithms, such information will
be specific to each tfm.  So the algorithm API needs to be changed to
pass the tfm structure instead of the context pointer.

This patch is basically a text substitution.  The only tricky bit is
the assembly routines that need to get the context pointer offset
through asm-offsets.h.

8b55ba0303 [CRYPTO] aes-i586: Get rid of useless function wrappers
The wrappers aes_encrypt/aes_decrypt simply reverse the order of the
function arguments.  It's just as easy to get the actual assembly code
to read them in the opposite order.

e6a3a925a2 [CRYPTO] aes-i586: Nano-optimisation on key length check
Reduce the number of comparisons by one through the use of jb/je.
This patch also corrects the comments regarding the different key
lengths.

c8a19c91b5 [CRYPTO] Allow AES C/ASM implementations to coexist
As the Crypto API now allows multiple implementations to be registered
for the same algorithm, we no longer have to play tricks with Kconfig
to select the right AES implementation.

This patch sets the driver name and priority for all the AES
implementations and removes the Kconfig conditions on the C implementation
for AES.

06ace7a9ba [CRYPTO] Use standard byte order macros wherever possible
A lot of crypto code needs to read/write a 32-bit/64-bit words in a
specific gender.  Many of them open code them by reading/writing one
byte at a time.  This patch converts all the applicable usages over
to use the standard byte order macros.

This is based on a previous patch by Denis Vlasenko.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
