Instead of loading the message words into both MSG and \m0 and then adding the round constants to MSG, load the message words into \m0 and the round constants into MSG and then add \m0 to MSG. This shortens the source code slightly. It changes the instructions slightly, but it doesn't affect binary code size and doesn't seem to affect performance.

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 reStructuredText 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.
