The HIFN driver is currently selectable on s390 but wont compile.
Since it looks like HIFN needs PCI make the Kconfig dependent on PCI,
which is not available on s390.

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.

The code waits in a busy loop until the hardware finishes the encryption
or decryption process. This wants a cpu_relax() :)
The busy loop finishes either if the encryption is done or if the counter
is zero. If the latter is true than the hardware failed. Since this
should not happen, leave sith a BUG().

It is enough if the IV is copied before and after the while loop.
With DM-Crypt is seems not be required to save the IV after encrytion
because a new one is used in the request (dunno about other users).
It is not save to load the IV within while loop and not save afterwards
because we mill end up with the wrong IV if the request goes consists
of more than one page.

The previous patch fixed spurious read faults from occuring by copying
the data if we happen to have a single block at the end of a page. It
appears that gcc cannot guarantee 16-byte alignment in the kernel with
__attribute__. The following report from Torben Viets shows a buffer
that's only 8-byte aligned:
> eneral protection fault: 0000 [#1]

> esi: f7e89dc8 edi: f7639ff0 ebp: 00010000 esp: f7e89dc8
Since the hardware must have 16-byte alignment, the following patch fixes
this by open coding the alignment adjustment.

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.

Allow in-place crypto operations. Also remove the coherent user flag
(we use it automagically now), and by default use the user written
key rather then the HW hidden key - this makes crypto just work without

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).

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.

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,

type.

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.
