Back when we added SMAP support, all versions of binutils didn't necessarily understand the 'clac' and 'stac' instructions. So we implemented those instructions manually as ".byte" sequences. But we've since upgraded the minimum version of binutils to version 2.25, and that included proper support for the SMAP instructions, and there's no reason for us to use some line noise to express them any more.

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.
