kernel/params.c: downgrade warning for unsafe parameters
...
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.
