Following what was done in drm_cache.c, when the stub for
remap_io_mapping() was added in commit 67c430bbaae1 ("drm/i915: Skip
remap_io_mapping() for non-x86 platforms"), it included a log message
with pr_err(). However just the warning is already enough and switching
to WARN_ONCE() allows us to keep the log message while avoiding log
spam.

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.
