Sure, attached. Sorry about the trouble, the conflict was due to a
helper function added upstream.

Subject: [PATCH] drm/amdgpu: Keep track of amount of pinned CPU visible VRAM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Instead of CPU invisible VRAM. Preparation for the following, no
functional change intended.
v2:
* Also change amdgpu_vram_mgr_bo_invisible_size to
amdgpu_vram_mgr_bo_visible_size, allowing further simplification
