Mainline Linux tree for various devices, only for fun :)

This adds an optional function table on GEM objects. The main benefit is for drivers that support more than one type of memory (shmem,vram,cma) for their buffers depending on the hardware it runs on. With the callbacks attached to the GEM object itself, it is easier to have core helpers for the the various buffer types. The driver only has to make the decision about buffer type on GEM object creation and all other callbacks can be handled by the chosen helper. drm_driver->gem_prime_res_obj has not been added since there's a todo to put a reservation_object into drm_gem_object. v3: Add todo entry v2: Drop drm_gem_object_funcs->prime_mmap in favour of drm_gem_prime_mmap() (Daniel Vetter) v1: - drm_gem_object_funcs.map -> .prime_map let it only do PRIME mmap like the function it superseeds (Daniel Vetter) - Flip around the if ladders and make obj->funcs the first choice highlighting the fact that this the new default way of doing it (Daniel Vetter) Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181110145647.17580-4-noralf@tronnes.org |

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.
