Pull crypto updates from Herbert Xu:
- New cipher/hash driver for ARM ux500.
- Code clean-up for aesni-intel.
- Misc fixes.
Fixed up conflicts in arch/arm/mach-ux500/devices-common.h, where quite
frankly some of it made no sense at all (the pull brought in a
declaration for the dbx500_add_platform_device_noirq() function, which
neither exists nor is used anywhere).
Also some trivial add-add context conflicts in the Kconfig file in
drivers/{char/hw_random,crypto}/
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: aesni-intel - move more common code to ablk_init_common
crypto: aesni-intel - use crypto_[un]register_algs
crypto: ux500 - Cleanup hardware identification
crypto: ux500 - Update DMA handling for 3.4
mach-ux500: crypto - core support for CRYP/HASH module.
crypto: ux500 - Add driver for HASH hardware
crypto: ux500 - Add driver for CRYP hardware
hwrng: Kconfig - modify default state for atmel-rng driver
hwrng: omap - use devm_request_and_ioremap
crypto: crypto4xx - move up err_request_irq label
crypto, xor: Sanitize checksumming function selection output
crypto: caam - add backward compatible string sec4.0

Hardware Random Number Generator Core infrastructure.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called rng-core. This provides a device
|
|
that's usually called /dev/hw_random, and which exposes one
|
|
of possibly several hardware random number generators.
|
|
|
|
These hardware random number generators do not feed directly
|
|
into the kernel's random number generator. That is usually
|
|
handled by the "rngd" daemon. Documentation/hw_random.txt
|
|
has more information.

config UML_RANDOM

tristate "Hardware random number generator"
|
|
help
|
|
This option enables UML's "hardware" random number generator. It
|
|
attaches itself to the host's /dev/random, supplying as much entropy
|
|
as the host has, rather than the small amount the UML gets from its
|
|
own drivers. It registers itself as a standard hardware random number
|
|
generator, major 10, minor 183, and the canonical device name is
|
|
/dev/hwrng.
|
|
The way to make use of this is to install the rng-tools package
|
|
(check your distro, or download from
|
|
http://sourceforge.net/projects/gkernel/). rngd periodically reads
|
|
/dev/hwrng and injects the entropy into /dev/random.
