This patchsets exported some of the common functions implemented by
the SM4 AESNI/AVX algorithm, and reused these functions to achieve
the acceleration of AESNI/AVX2 implementation.
The main algorithm implementation comes from SM4 AES-NI work by
libgcrypt and Markku-Juhani O. Saarinen at:
https://github.com/mjosaarinen/sm4ni
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:

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.

Export the reusable functions in the SM4 AESNI/AVX implementation,
mainly public functions, which are used to develop the SM4 AESNI/AVX2
implementation, and eliminate unnecessary duplication of code.
At the same time, in order to make the public function universal,
minor fixes was added.

2.19.1.3.ge56e4f7
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:

These functions need bracketing by kernel_fpu_enable()
(or whatever it is called.)
That will significantly affect the performance.
Also the functions look pretty big (I don't know how big
the generic ones are) and will take time to load into the I$
and will displace other code.
So while a hot-cache benchmark might show improvements
for repeated calls is isn't obvious that any significant
gain will be made for real-life calls which could easily
be of single buffers.

Yes, the functions bracketed by kernel_fpu_begin() do affect
performance. It seems that the kernel can only do this, so by processing
as much data as possible in a kernel_fpu_begin/end() operation to
improve performance. actually do it now.
