Subject: linux-next: build failure after merge of the drm tree

Hi Dave,

After merging the drm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:818:6: error: redefinition of 'amdgpu_ttm_tt_affect_userptr'
 bool amdgpu_ttm_tt_affect_userptr(struct ttm_tt *ttm, unsigned long start,
      ^
drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:799:6: note: previous definition of 'amdgpu_ttm_tt_affect_userptr' was here
 bool amdgpu_ttm_tt_affect_userptr(struct ttm_tt *ttm, unsigned long start,
      ^

Caused by a bad git resolution in commit

  971f3e7dd355 ("Merge remote-tracking branch 'drm/drm-next'")

I have added the following as a merge fix up patch and can carry it
as necessary.
