Subject: drm/amd/amdgpu: Remove AMDGPU tracepoint and use new TTM tracepoint
 (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Switches the AMDGPU driver over to the TTM tracepoint and removes
our old one.  Now you can enable traces before loading the module
and trace all mappings.

(v2): Use struct device instead of pci in trace.
