866cd902e8 [CRYPTO] padlock: Only reset the key once for each CBC and ECB operation
Currently we reset the key for each segment fed to the xcrypt instructions.
This patch optimises this for CBC and ECB so that we only do this once for
each encrypt/decrypt operation.

653ebd9c85 [CRYPTO] blkcipher: Merge ablkcipher and blkcipher into one option/module
With the impending addition of the givcipher type, both blkcipher and
ablkcipher algorithms will use it to create givcipher objects.  As such
it no longer makes sense to split the system between ablkcipher and
blkcipher.  In particular, both ablkcipher.c and blkcipher.c would need
to use the givcipher type which has to reside in ablkcipher.c since it
shares much code with it.

This patch merges the two Kconfig options as well as the modules into one.

37a8023ce5 [HIFN]: Improve PLL initialization
The current PLL initalization has a number of deficiencies:

- uses fixed multiplier of 8, which overclocks the chip when using a
  reference clock that operates at frequencies above 33MHz. According
  to a comment in the BSD source, this is true for the external clock
  on almost all every board.

- writes to a reserved bit

- doesn't follow the initialization procedure specified in chapter
  6.11.1 of the HIFN hardware users guide

- doesn't allow to use the PCI clock

This patch adds a module parameter to specify the reference clock
(pci or external) and its frequency and uses that to calculate the
optimum multiplier to reach the maximal speed. By default it uses
the external clock and assumes a speed of 66MHz, which effectively
halfs the frequency currently used.

332f8840f7 [CRYPTO] ablkcipher: Add distinct ABLKCIPHER type
Up until now we have ablkcipher algorithms have been identified as
type BLKCIPHER with the ASYNC bit set.  This is suboptimal because
ablkcipher refers to two things.  On the one hand it refers to the
top-level ablkcipher interface with requests.  On the other hand it
refers to and algorithm type underneath.

As it is you cannot request a synchronous block cipher algorithm
with the ablkcipher interface on top.  This is a problem because
we want to be able to eventually phase out the blkcipher top-level
interface.

This patch fixes this by making ABLKCIPHER its own type, just as
we have distinct types for HASH and DIGEST.  The type it associated
with the algorithm implementation only.

Which top-level interface is used for synchronous block ciphers is
then determined by the mask that's used.  If it's a specific mask
then the old blkcipher interface is given, otherwise we go with the
new ablkcipher interface.

a1e6ef2f1e [CRYPTO] hifn: Schedule callback invocation to tasklet.
This patch forces HIFN driver to invoke crypto request callbacks from
tasklet (softirq context) instead of hardirq context, since network
stack expects it to be called from bottom halves.

It is done by simply scheduling callback invocation via dedicated
tasklet. Workqueue solution was dropped because of tooo slow
rescheduling performance (7 times slower than tasklet, for mode details
one can check this link:
http://tservice.net.ru/~s0mbre/blog/devel/other/2007_11_09.html).

Driver passed all AES and DES tests in tcryt.c module.

490fe3f05b [CRYPTO] padlock: Fix alignment fault in aes_crypt_copy
The previous patch fixed spurious read faults from occuring by copying

that's only 8-byte aligned:

ad5d27899f [CRYPTO] sha: Load the SHA[1|256] module by an alias
Loading the crypto algorithm by the alias instead of by module directly
has the advantage that all possible implementations of this algorithm
are loaded automatically and the crypto API can choose the best one
depending on its priority.

Additionally it ensures that the generic implementation as well as the
HW driver (if available) is loaded in case the HW driver needs the
generic version as fallback in corner cases.

Also remove the probe for sha1 in padlock's init code.

Quote from Herbert:
  The probe is actually pointless since we can always probe when
  the algorithm is actually used which does not lead to dead-locks
  like this.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

6010439f47 [CRYPTO] padlock: Convert padlock-sha to use crypto_hash
This patch converts padlock-sha to use crypto_hash for its fallback.
It also changes the fallback selection to use selection by type instead
of name.  This is done through the new CRYPTO_ALG_NEED_FALLBACK bit,
which is set if and only if an algorithm needs a fallback of the same
type.

efcf8023e2 [CRYPTO] drivers: Remove obsolete block cipher operations
This patch removes obsolete block operations of the simple cipher type
from drivers.  These were preserved so that existing users can make a
smooth transition.  Now that the transition is complete, they are no
longer needed.

28ce728a90 [CRYPTO] padlock: Added block cipher versions of CBC/ECB
This patch adds block cipher algorithms for cbc(aes) and ecb(aes) for
the PadLock device.  Once all users to the old cipher type have been
converted the old cbc/ecb PadLock operations will be removed.

560c06ae1a [CRYPTO] api: Get rid of flags argument to setkey
Now that the tfm is passed directly to setkey instead of the ctx, we no
longer need to pass the &tfm->crt_flags pointer.

This patch also gets rid of a few unnecessary checks on the key length
for ciphers as the cipher layer guarantees that the key length is within
the bounds specified by the algorithm.

Rather than testing dia_setkey every time, this patch does it only once
during crypto_alloc_tfm.  The redundant check from crypto_digest_setkey
is also removed.

5644bda5d6 [CRYPTO] padlock: Helper module padlock.ko
Compile a helper module padlock.ko that will try
to autoload all configured padlock algorithms.

This also provides backward compatibility with 
the ancient times before padlock.ko was renamed 
to padlock-aes.ko
