+Subject: [PATCH] drm/radeon: force dma32 to fix regression rs4xx,rs6xx,rs740
+
+It seems some of those IGP dislike non dma32 page despite what
+documentation says. Fix regression since we allowed non dma32
+pages. It seems it only affect some revision of those IGP chips
+as we don't know which one just force dma32 for all of them.
