Arnaldo Carvalho de Melo 01f97511f1 tools headers uapi: Synchronize i915_drm.h 
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:

  --- /tmp/build/perf/trace/beauty/generated/ioctl/drm_ioctl_array.c.old 2018-04-05 14:38:33.660111995 -0300
  +++ /tmp/build/perf/trace/beauty/generated/ioctl/drm_ioctl_array.c 2018-04-05 14:40:17.923283914 -0300

          [DRM_COMMAND_BASE + 0x36] = "I915_PERF_OPEN",
          [DRM_COMMAND_BASE + 0x37] = "I915_PERF_ADD_CONFIG",
          [DRM_COMMAND_BASE + 0x38] = "I915_PERF_REMOVE_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
  4346.246 ( 0.002 ms): gnome-shell/1455 ioctl(fd: 8</dev/dri/card0>, cmd: DRM_I915_GEM_MADVISE, arg: 0x7fff3b0cd980) = 0
  4346.252 ( 0.002 ms): gnome-shell/1455 ioctl(fd: 8</dev/dri/card0>, cmd: DRM_I915_GEM_BUSY, arg: 0x7fff3b0cdb00) = 0
<SNIP>

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'

README 

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.
