<b>Subject:</b> [PATCH 1/2] drm/amdgpu: use zero as start for dummy resource walks</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">When we don't have a physically backing store we should use zero instead<br>
of the virtual start address since that isn't necessary a valid physical<br>
one.<br>
