6aeb49bc5a crypto: sha256 - use crypto_[un]register_shashes
Combine all shash algs to be registered and use new crypto_[un]register_shashes
functions. This simplifies init/exit code.

9b2fda7b94 crypto: sha256_generic - Add export/import support
This patch adds export/import support to sha256_generic.  The exported
type is defined by struct sha256_state, which is basically the entire
descriptor state of sha256_generic.

3d4d277cf8 crypto: sha256_generic - Use 64-bit counter like sha1
This patch replaces the two 32-bit counter code in sha256_generic
with the simpler 64-bit counter code from sha1.

Thanks for the suggestion, the init() is replaced with

	<algorithm name>_mod_init ()

and fini () is replaced with <algorithm name>_mod_fini.

cd12fb906d [CRYPTO] sha256-generic: Extend sha256_generic.c to support SHA-224
Resubmitting this patch which extends sha256_generic.c to support SHA-224 as
described in FIPS 180-2 and RFC 3874. HMAC-SHA-224 as described in RFC4231
is then supported through the hmac interface.

Patch includes test vectors for SHA-224 and HMAC-SHA-224.

SHA-224 chould be chosen as a hash algorithm when 112 bits of security
strength is required.

Patch generated against the 2.6.24-rc1 kernel and tested against
2.6.24-rc1-git14 which includes fix for scatter gather implementation for HMAC.

87ae9afdca cleanup asm/scatterlist.h includes
Not architecture specific code should not #include <asm/scatterlist.h>.

This patch therefore either replaces them with
#include <linux/scatterlist.h> or simply removes them if they were
unused.

5265eeb2b0 [CRYPTO] sha: Add header file for SHA definitions
There are currently several SHA implementations that all define their own
initialization vectors and size values. Since this values are idential
move them to a header file under include/crypto.

ad5d27899f [CRYPTO] sha: Load the SHA[1|256] module by an alias
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.
