The x86 SHA-256 module contains four implementations: SSSE3, AVX, AVX2,
and SHA-NI. Commit 1c43c0f1f8 ("crypto: x86/sha - load modules based
on CPU features") made the module be autoloaded when SSSE3, AVX, or AVX2
is detected. The omission of SHA-NI appears to be an oversight, perhaps
because of the outdated file-level comment. This patch fixes this,
though in practice this makes no difference because SSSE3 is a subset of
the other three features anyway. Indeed, sha256_ni_transform() executes
SSSE3 instructions such as pshufb.

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.
