+Subject: [PATCH] nouveau/nvc0: increase overallocation on shader bo to 2K
+
+I've been seeing a bunch of read page faults at the end of the
+shader allocation, nvk uses a full page at the end to overallocate
+so align with that and see if it goes away.
+
+ahulliet and skeggsb both said 2k was used.
