Eric Biggers d45a90cb5d crypto: sm3 - fix undefined shift by >= width of value
sm3_compress() calls rol32() with shift >= 32, which causes undefined
behavior.  This is easily detected by enabling CONFIG_UBSAN.

Explicitly AND with 31 to make the behavior well defined.

Fixes: 4f0fc1600e ("crypto: sm3 - add OSCCA SM3 secure hash")

README

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.
