Patches #1-#4 are Reviewed-by: Christian König <christian.koenig@xxxxxxx>

Patches #5 and #6 are Acked-by: Christian König <christian.koenig@xxxxxxx>

Patch #7 already has my rb.

I would say push that to drm-misc-next ASAP.

Christian.

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.

v4:
	* rebase on top of amdgpu hot-unplug changes
v3:
	* tidy up the new mmap functions in amdgpu and radeon (Christian)
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

   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
