To pick up the changes in:

  c822e05918 drm/i915: expose rcs topology through query uAPI
  a446ae2c6e drm/i915: add query uAPI

This affects 'perf trace', that automagically gets the definition of the
new I915_QUERY DRM ioctl:

          [DRM_COMMAND_BASE + 0x36] = "I915_PERF_OPEN",
          [DRM_COMMAND_BASE + 0x37] = "I915_PERF_ADD_CONFIG",

  +       [DRM_COMMAND_BASE + 0x39] = "I915_QUERY",
   };

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
<SNIP>
  4346.232 ( 0.012 ms): gnome-shell/1455 ioctl(fd: 8</dev/dri/card0>, cmd: DRM_I915_GEM_BUSY, arg: 0x7fff3b0cd910) = 0

This silences this perf tools build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/drm/i915_drm.h' differs from latest version at 'include/uapi/drm/i915_drm.h'
