As requested, this patch sets the default to y and removes the
EMBEDDED dependency.

crypto: testmgr - Fix test disabling option

2010-08-06T01:40:28+00:00

This patch fixes a serious bug in the test disabling patch where
it can cause an spurious load of the cryptomgr module even when
it's compiled in.

It also negates the test disabling option so that its absence
causes tests to be enabled.

The Kconfig option is also now behind EMBEDDED.

crypto: testmgr - add an option to disable cryptoalgos' self-tests

2010-06-03T10:53:43+00:00

By default, CONFIG_CRYPTO_MANAGER_TESTS will be enabled and thus
self-tests will still run, but it is now possible to disable them
to gain some time during bootup.

crypto: pcomp - Fix illegal Kconfig configuration

2010-06-03T10:33:06+00:00

The PCOMP Kconfig entry current allows the following combination
which is illegal:

ZLIB=y
PCOMP=y
ALGAPI=m
ALGAPI2=y
MANAGER=m
MANAGER2=m

This patch fixes this by adding PCOMP2 so that PCOMP can select
ALGAPI to propagate the setting to MANAGER2.

crypto: pcrypt - Add pcrypt crypto parallelization wrapper

2010-01-07T04:57:19+00:00

This patch adds a parallel crypto template that takes a crypto
algorithm and converts it to process the crypto transforms in
parallel. For the moment only aead algorithms are supported.

crypto: ghash - Add PCLMULQDQ accelerated implementation

2009-10-19T02:53:06+00:00

PCLMULQDQ is used to accelerate the most time-consuming part of GHASH,
carry-less multiplication. More information about PCLMULQDQ can be
found at:

http://software.intel.com/en-us/articles/carry-less-multiplication-and-its-usage-for-computing-the-gcm-mode/

Because PCLMULQDQ changes XMM state, its usage must be enclosed with
kernel_fpu_begin/end, which can be used only in process context, the
acceleration is implemented as crypto_ahash. That is, request in soft
IRQ context will be defered to the cryptd kernel thread.
