[RFC PATCH 0/2] drm/amdgpu: Convert to ttm_bo_vmap()

[Thomas Zimmermann]

Convert amdgpu to use ttm_bo_vmap() instead of ttm_bo_kmap(). The
latter is deprecated. Passing ttm_bo_vmap()'s locking validation 
requires to remove the implicit unmap from the BO release path.

Smoke-tested with an Radeon RX 460.

There's similar patchset for xe at [1], which requires additional
changes.
