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.Signed-off-by: Jan Glauber

This patch moves the config options for the s390 crypto instructions
to the standard "Hardware crypto devices" menu. In addition some
cleanup has been done: use a flag for supported keylengths, add a
warning about machien limitation, return ENOTSUPP in case the
hardware has no support, remove superfluous printks and update
email addresses.Signed-off-by: Jan Glauber

Major cleanup of all s390 inline assemblies. They now have a common
coding style. Quite a few have been shortened, mainly by using register
asm variables. Use of the EX_TABLE macro helps as well. The atomic ops,
bit ops and locking inlines new use the Q-constraint if a newer gcc
is used. That results in slightly better code.Thanks to Christian Borntraeger for proof reading the changes.

This patch adds block cipher algorithms for S390. Once all users of the
old cipher type have been converted the existing CBC/ECB non-block cipher
operations will be removed.Signed-off-by: Herbert Xu

Accelerated versions of crypto algorithms must carry a distinct driver name
and priority in order to distinguish themselves from their generic counter-
part.Signed-off-by: Herbert Xu

Sanitize some s390 Kconfig options. We have ARCH_S390, ARCH_S390X,
ARCH_S390_31, 64BIT, S390_SUPPORT and COMPAT. Replace these 6 options by
S390, 64BIT and COMPAT.Signed-off-by: Martin Schwidefsky

Replace all references to z990 by s390 in the in-kernel crypto files in
arch/s390/crypto. The code is not specific to a particular machine (z990) but
to the s390 platform. Big diff, does nothing..Signed-off-by: Jan Glauber
