drm/amdgpu: fix dependency issue

2017-05-10T17:23:53+00:00

The problem is that executing the jobs in the right order doesn't give you the right result
because consecutive jobs executed on the same engine are pipelined.
In other words job B does it buffer read before job A has written it's result.

2017-04-28T21:32:47+00:00

Use amdgpu_vm_bo_update_mapping() instead of amdgpu_vm_bo_split_mapping() here.

We don't want any flags set in the cleared areas and splitting
shouldn't be necessary.
