Herbert Xu 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.

Herbert Xu 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.

Brian Gerst 0d078f6f96 [PATCH] CONFIG_IA32
Add CONFIG_X86_32 for i386.  This allows selecting options that only apply
to 32-bit systems.

(X86 && !X86_64) becomes X86_32
(X86 ||  X86_64) becomes X86

Herbert Xu 476df259cd [CRYPTO] Update IV correctly for Padlock CBC encryption
When the Padlock does CBC encryption, the memory pointed to by EAX is
not updated at all.  Instead, it updates the value of EAX by pointing
it to the last block in the output.  Therefore to maintain the correct
semantics we need to copy the IV.

Herbert Xu fbdae9f3e7 [CRYPTO] Ensure cit_iv is aligned correctly
This patch ensures that cit_iv is aligned according to cra_alignmask
by allocating it as part of the tfm structure.  As a side effect the
crypto layer will also guarantee that the tfm ctx area has enough space
to be aligned by cra_alignmask.  This allows us to remove the extra
space reservation from the Padlock driver.

Herbert Xu 28e8c3ad94 [PADLOCK] Implement multi-block operations
By operating on multiple blocks at once, we expect to extract more
performance out of the VIA Padlock.

Herbert Xu 6789b2dc45 [PADLOCK] Move fast path work into aes_set_key and upper layer
Most of the work done aes_padlock can be done in aes_set_key.  This
means that we only have to do it once when the key changes rather
than every time we perform an encryption or decryption.

This patch also sets cra_alignmask to let the upper layer ensure
that the buffers fed to us are aligned correctly.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
