The implementation is based on the 32-bit implementation of the aria.
Also, aria-avx process steps are the similar to the camellia-avx.
1. Byteslice(16way)
2. Add-round-key.
3. Sbox
4. Diffusion layer.

Except for s-box, all steps are the same as the aria-generic
implementation. s-box step is very similar to camellia and
sm4 implementation.

There are 2 implementations for s-box step.
One is to use AES-NI and affine transformation, which is the same as
Camellia, sm4, and others.
Another is to use GFNI.
GFNI implementation is faster than AES-NI implementation.
So, it uses GFNI implementation if the running CPU supports GFNI.

There are 4 s-boxes in the ARIA and the 2 s-boxes are the same as
AES's s-boxes.

To calculate the first sbox, it just uses the aesenclast and then
inverts shift_row.
No more process is needed for this job because the first s-box is
the same as the AES encryption s-box.

To calculate the second sbox(invert of s1), it just uses the aesdeclast
and then inverts shift_row.
No more process is needed for this job because the second s-box is
the same as the AES decryption s-box.

To calculate the third s-box, it uses the aesenclast,
then affine transformation, which is combined AES inverse affine and
ARIA S2.

To calculate the last s-box, it uses the aesdeclast,
then affine transformation, which is combined X2 and AES forward affine.

The optimized third and last s-box logic and GFNI s-box logic are
implemented by Jussi Kivilinna.

The aria-generic implementation is based on a 32-bit implementation,
not an 8-bit implementation. the aria-avx Diffusion Layer implementation
is based on aria-generic implementation because 8-bit implementation is
not fit for parallel implementation but 32-bit is enough to fit for this.

<title>crypto: blake2s - remove shash module</title>

BLAKE2s has no currently known use as an shash. Just remove all of this
unnecessary plumbing. Removing this shash was something we talked about
back when we were making BLAKE2s a built-in, but I simply never got
around to doing it. So this completes that project.

Importantly, this fixs a bug in which the lib code depends on
crypto_simd_disabled_for_test, causing linker errors.

Also add more alignment tests to the selftests and compare SIMD and
non-SIMD compression functions, to make up for what we lose from
testmgr.c.

<id>urn:sha1:34f7f6c3011276313383099156be287ac745bcea</id>
<content type='text'>
Add hardware accelerated version of POLYVAL for x86-64 CPUs with
PCLMULQDQ support.

This implementation is accelerated using PCLMULQDQ instructions to
perform the finite field computations.  For added efficiency, 8 blocks
of the message are processed simultaneously by precomputing the first
8 powers of the key.

Schoolbook multiplication is used instead of Karatsuba multiplication
because it was found to be slightly faster on x86-64 machines.
Montgomery reduction must be used instead of Barrett reduction due to
the difference in modulus between POLYVAL's field and other finite
fields.

More information on POLYVAL can be found in the HCTR2 paper:
"Length-preserving encryption with HCTR2":

This patch adds AVX assembly accelerated implementation of SM3 secure
hash algorithm. From the benchmark data, compared to pure software
implementation sm3-generic, the performance increase is up to 38%.

The main algorithm implementation based on SM3 AES/BMI2 accelerated
work by libgcrypt at:
https://gnupg.org/software/libgcrypt/index.html

Benchmark on Intel i5-6200U 2.30GHz, performance data of two
implementations, pure software sm3-generic and sm3-avx acceleration.
The data comes from the 326 mode and 422 mode of tcrypt. The abscissas
are different lengths of per update. The data is tabulated and the
unit is Mb/s:

In preparation for using blake2s in the RNG, we change the way that it
is wired-in to the build system. Instead of using ifdefs to select the
right symbol, we use weak symbols. And because ARM doesn't need the
generic implementation, we make the generic one default only if an arch
library doesn't need it already, and then have arch libraries that do
need it opt-in. So that the arch libraries can remain tristate rather
than bool, we then split the shash part from the glue code.

Like the implementation of AESNI/AVX, this patch adds an accelerated
implementation of AESNI/AVX2. In terms of code implementation, by
reusing AESNI/AVX mode-related codes, the amount of code is greatly
reduced. From the benchmark data, it can be seen that when the block
size is 1024, compared to AVX acceleration, the performance achieved
by AVX2 has increased by about 70%, it is also 7.7 times of the pure
software implementation of sm4-generic.

The main algorithm implementation comes from SM4 AES-NI work by
libgcrypt and Markku-Juhani O. Saarinen at:
https://github.com/mjosaarinen/sm4ni

This optimization supports the four modes of SM4, ECB, CBC, CFB,
and CTR. Since CBC and CFB do not support multiple block parallel
encryption, the optimization effect is not obvious.

Benchmark on Intel i5-6200U 2.30GHz, performance data of three
implementation methods, pure software sm4-generic, aesni/avx
acceleration, and aesni/avx2 acceleration, the data comes from
the 218 mode and 518 mode of tcrypt. The abscissas are blocks of
different lengths. The data is tabulated and the unit is Mb/s:

This patch adds AES-NI/AVX/x86_64 assembler implementation of SM4
block cipher. Through two affine transforms, we can use the AES S-Box
