+Subject: [PATCH] radeonsi: On Aarch64 force persistent buffers to GTT
+
+This fixes a glamore corruption issue on the HoneyComb and by
+internet reports should also fix problems seen on Huaweii
+Kunpeng hardware.
+
+The root cause of the corruption needs to be worked out, but
+this patch also adds a noticable performance improvement. The
+aquarium webgl demo under chromium increases from 39-49 FPS
+when 5000 fish being rendered is selected.  Glmark scores also
+improve by ~200 with no specific tests showing any regression.
