Sebastian Siewior 7dc748e4e7 [CRYPTO] padlock-aes: Use generic setkey function
The Padlock AES setkey routine is the same as exported by the generic
implementation. So we could use it.

Ralph Wuerthner 2f7c8bd6dc [S390] zcrypt: add support for large random numbers
This patch allows user space applications to access large amounts of
truly random data. The random data source is the build-in hardware
random number generator on the CEX2C cards.

Jan Glauber 3f5615e012 [S390] crypto: move s390 Kconfig options.
Move s390 crypto Kconfig options to drivers/crypto/Kconfig to have all
hardware crypto devices in one place.

This also makes messing up the kernel source tree easier for some people.

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.

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.

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!
