* generations Kepler requires that we use small pages (4K) for cursor scanout surfaces. The
* proper fix for this is to teach nouveau to migrate fbs being used for the cursor plane to
* small page allocations in prepare_fb(). When this is implemented, we should also force
* large pages (128K) for ovly fbs in order to fix Kepler ovlys.
* But until then, just limit cursors to 128x128 - which is small enough to avoid ever using
* large pages.
