+Subject: [PATCH 1626/2940] drm/amdgpu: revert "cleanup setting bulk_movable"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit 4ef27005fefd4be102010b7d8552fec1ee13435a.
+
+It can trigger a reference counter bug in TTM. Need to investigate further, but
+for now revert the offending change.
