This patch does not add new features, but only refactors and simplifies the implementation of the Crypto Extension acceleration of the SM4 algorithm: Extract the macro optimized by SM4 Crypto Extension for reuse in the subsequent optimization of CCM/GCM modes. Encryption in CBC and CFB modes processes four blocks at a time instead of one, allowing the ld1 instruction to load 64 bytes of data at a time, which will reduces unnecessary memory accesses. CBC/CFB/CTR makes full use of free registers to reduce redundant memory accesses, and rearranges some instructions to improve out-of-order execution capabilities.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
