To pick up the changes in:
c822e0591855 drm/i915: expose rcs topology through query uAPI
a446ae2c6e65 drm/i915: add query uAPI
This affects 'perf trace', that automagically gets the definition of the
new I915_QUERY DRM ioctl:

I.e. on systems where this is used it will appear when, for instance,
one does a system wide 'perf trace' session looking for ioctl calls,
just like it does with the previously implemented DRM_I915 ioctls:
# perf trace -e ioctl --filter-pids 2190

This silences this perf tools build warning:

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
