As using an unsafe module parameter is, by its very definition, an expected user action, emitting a warning is overkill. Nothing has yet gone wrong, and we add a taint flag for any future oops should something actually go wrong. So instead of having a user controllable pr_warn, downgrade it to a pr_notice for "a normal, but significant condition". We make use of unsafe kernel parameters in igt (https://cgit.freedesktop.org/drm/igt-gpu-tools/) (we have not yet succeeded in removing all such debugging options), which generates a warning and taints the kernel. The warning is unhelpful as we then need to filter it out again as we check that every test themselves do not provoke any kernel warnings.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
