Implement mmap via struct drm_gem_object_functions.mmap in amdgpu,
radeon and nouveau. This allows for using common DRM helpers for
the mmap-related callbacks in struct file_operations and struct
drm_driver. The drivers have their own vm_ops, which are now set
automatically by the DRM core functions. The code in each driver's
verify_access becomes part of the driver's new mmap implementation.
With the GEM drivers converted, vmwgfx is the only user of
ttm_bo_mmap() and related infrastructure. So move everything into
vmwgfx and delete the rsp code from TTM.
This touches several drivers. Preferably everything would be merged
at once via drm-misc-next.
v2:
* removal of amdgpu fbdev mmap already merged (Christian)
* rebase on top of amdgpu fixes [1] (Felix)
* replace pr_err() with drm_err() in vmwgfx patch (Zack)
* several typos

Thomas Zimmermann (7):
drm/ttm: Don't override vm_ops callbacks, if set
drm/amdgpu: Implement mmap as GEM object function
drm/radeon: Implement mmap as GEM object function
drm/nouveau: Implement mmap as GEM object function
drm/vmwgfx: Inline ttm_bo_mmap() into vmwgfx driver
drm/vmwgfx: Inline vmw_verify_access()
drm/ttm: Remove ttm_bo_mmap() and friends
