Herbert Xu 946fef4e14 [CRYPTO] hifn795x: Disallow built-in hifn795x when HW_RANDOM is m
Currently it is possible to select HW_RANDOM as a module and have
hifn795x built-in.  This causes a build problem because hifn795x
will then call hwrng_register which isn't built-in.

This patch introduces a new config option to control the hifn795x
RNG which lets us avoid this problem.

Herbert Xu 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.

Patrick McHardy 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.

Herbert Xu 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.

Evgeniy Polyakov 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).

The previous patch fixed spurious read faults from occuring by copying

that's only 8-byte aligned:

Since the hardware must have 16-byte alignment, the following patch fixes
this by open coding the alignment adjustment.

Sebastian Siewior 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.

  The probe is actually pointless since we can always probe when
  the algorithm is actually used which does not lead to dead-locks

When it's a module it isn't doing anything special, the same functionality 
can be provided in userspace by "probeall padlock padlock-aes padlock-sha" 
in modules.conf if it is required.

Tim Schmielau 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).

Jan Glauber 1b27829489 [S390] Support for s390 Pseudo Random Number Generator
Starting with the z9 the CPU Cryptographic Assist Facility comes with
an integrated Pseudo Random Number Generator. The generator creates
random numbers by an algorithm similar to the ANSI X9.17 standard.
The pseudo-random numbers can be accessed via a character device driver
node called /dev/prandom. Similar to /dev/urandom any amount of bytes
can be read from the device without blocking.
