While running my branch profiler that checks for incorrect "likely" and "unlikely"s around the kernel, there's a large number of them that are incorrect due to being "static_branches". As static_branches are rather special, as they are likely or unlikely for other reasons than normal annotations are used for, there's no reason to have them be profiled. Expose the "unlikely_notrace" and "likely_notrace" so that the static_branch can use them, and have them be ignored by the branch profilers.

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.
