2194a63a81 drm: Add library for shmem backed GEM objects 
This adds a library for shmem backed GEM objects.

v8:
- export drm_gem_shmem_create_with_handle
- call mapping_set_gfp_mask to set default zone to GFP_HIGHUSER
- Add helper drm_gem_shmem_get_pages_sgt()

v7:
- Use write-combine for mmap instead. This is the more common
  case. (robher)

v6:
- Fix uninitialized variable issue in an error path (anholt).
- Add a drm_gem_shmem_vm_open() to the fops to get proper refcounting
  of the pages (anholt).

v5:
- Drop drm_gem_shmem_prime_mmap() (Daniel Vetter)
- drm_gem_shmem_mmap(): Subtract drm_vma_node_start() to get the real
  vma->vm_pgoff
- drm_gem_shmem_fault(): Use vmf->pgoff now that vma->vm_pgoff is correct

v4:
- Drop cache modes (Thomas Hellstrom)
- Add a GEM attached vtable

v3:
- Grammar (Sam Ravnborg)
- s/drm_gem_shmem_put_pages_unlocked/drm_gem_shmem_put_pages_locked/
  (Sam Ravnborg)
- Add debug output in error path (Sam Ravnborg)

1ba627148e drm: Add reservation_object to drm_gem_object 
Many users of drm_gem_object embed a struct reservation_object into
their subclassed struct, so let's add one to struct drm_gem_object.
This will allow removing the reservation object from the subclasses
and removing the ->gem_prime_res_obj callback.

With the addition, add a drm_gem_reservation_object_wait() helper
function for drivers to use in wait ioctls.

badfa5be85 drm/doc: Make igts for cross-driver stuff strongly suggested 
Compared to the RFC[1] no changes to the patch itself, but igt moved
forward a lot:

- gitlab CI builds with: reduced configs/libraries, arm cross build
  and a sysroot build (should address all the build/cross platform
  concerns raised in the RFC discussions).

- tests reorganized into subdirectories so that the i915-gem tests
  don't clog the main/shared tests directory anymore

- quite a few more non-intel people contributing/reviewing/committing
  igt tests patches.

I think this addresses all the concerns raised in the RFC discussions,
and assuming there's enough Acks and no new issues that pop up, we can
go ahead with this.

v2:
- Use "should" (in the usual RFC sense) to make it clear that in the
  end this is all up to reviewer's discretion, as usual (Jani).
- Also in the title s/mandatory/strongly suggested/ (me)
- Make it clear we're not going to block features if a testcase is not
  feasible, given hw and state of igt, both having some good gaps in
  what can be tested (Harry, Eric, Sean, ...).
