From be50641f155e86f42c15ba1b3e77533e514316a4 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5319/5725] drm/amdgpu: fix up GDS/GWS/OA shifting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
That only worked by pure coincident. Completely remove the shifting and
always apply correct PAGE_SHIFT.
