Daniel Vetter f42e181935 drm/gem: Add DEFINE_DRM_GEM_FOPS
Sadly there's only 1 driver which can use it, everyone else is special
for some reason:

- gma500 has a horrible runtime PM ioctl wrapper that probably doesn't
  really work but meh.
- i915 needs special compat_ioctl handler because regrets.
- arcgpu needs to fixup the pgprot because (no idea why it can't do
  that in the fault handler like everyone else).
- tegra does even worse stuff with pgprot
- udl does something with vm_flags too ...
- cma helpers, etnaviv, mtk, msm, rockchip, omap all implement some
  variation on prefaulting.
- exynos is exynos, I got lost in the midlayers.
- vc4 has to reinvent half of cma helpers because those are too much
  midlayer, plus vm_flags dances.
- vgem also seems unhappy with the default vm_flags.

So pretty sad divergence and I'm sure we could do better, but not
really an idea. Oh well, maybe this macro here helps to encourage more
consistency at least going forward.

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.
