Hi 沈子俊,
Thanks for your patchset.
看到你发的这几组关于 SM3/4 相关的补丁集， 能否在下周五的 kernel sig 会上，给家大家介绍下这组特性， 比如，介绍下特性本身，社区状态，测试验证效果等。

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.
