Now that module softdeps are in the kernel we can use that to resolve
the boot issue which cause the revert.

Pull crypto fixes from Herbert Xu:
 "This push fixes a memory corruption issue in caam, as well as
  reverting the new optimised crct10dif implementation as it breaks boot
  on initrd systems.

  Hopefully crct10dif will be reinstated once the supporting code is
  added so that it doesn't break boot"

Unfortunately this change broke boot on some systems that used an
initrd which does not include the newly created crct10dif modules.
As these modules are required by sd_mod under certain configurations
this is a serious problem.

Revert "crypto: twofish - add AVX2/x86_64 assembler implementation of twofish cipher"

2013-06-21T06:44:29+00:00

This reverts commit cf1521a1a5e21fd1e79a458605c4282fbfbbeee2.

Instruction (vpgatherdd) that this implementation relied on turned out to be
slow performer on real hardware (i5-4570). The previous 8-way twofish/AVX
implementation is therefore faster and this implementation should be removed.

Converting this implementation to use the same method as in twofish/AVX for
table look-ups would give additional ~3% speed up vs twofish/AVX, but would
hardly be worth of the added code and binary size.

Instruction (vpgatherdd) that this implementation relied on turned out to be
slow performer on real hardware (i5-4570). The previous 4-way blowfish
implementation is therefore faster and this implementation should be removed.

crypto: crct10dif - Glue code to cast accelerated CRCT10DIF assembly as a crypto transform

2013-05-24T09:55:27+00:00

Glue code that plugs the PCLMULQDQ accelerated CRC T10 DIF hash into the
crypto framework.  The config CRYPTO_CRCT10DIF_PCLMUL should be turned
on to enable the feature.  The crc_t10dif crypto library function will
use this faster algorithm when crct10dif_pclmul module is loaded.

crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework

2013-05-20T12:11:01+00:00

When CRC T10 DIF is calculated using the crypto transform framework, we
wrap the crc_t10dif function call to utilize it.  This allows us to
take advantage of any accelerated CRC T10 DIF transform that is
plugged into the crypto framework.

crypto: camellia - add AVX2/AES-NI/x86_64 assembler implementation of camellia cipher

2013-04-25T13:09:07+00:00

Patch adds AVX2/AES-NI/x86-64 implementation of Camellia cipher, requiring
32 parallel blocks for input (512 bytes). Compared to AVX implementation, this
version is extended to use the 256-bit wide YMM registers. For AES-NI
instructions data is split to two 128-bit registers and merged afterwards.
Even with this additional handling, performance should be higher compared
to the AES-NI/AVX implementation.

crypto: serpent - add AVX2/x86_64 assembler implementation of serpent cipher

2013-04-25T13:09:07+00:00

Patch adds AVX2/x86-64 implementation of Serpent cipher, requiring 16 parallel
blocks for input (256 bytes). Implementation is based on the AVX implementation
and extends to use the 256-bit wide YMM registers. Since serpent does not use
table look-ups, this implementation should be close to two times faster than
the AVX implementation.
