commit 9176703788c66de8287c6224650b1ff8d4238126
Author: Marek Olšák <marek.olsak@amd.com>
Date:   Wed Aug 8 15:37:21 2018 -0400

    radeonsi: increase the maximum UBO size to 2 GB
    
    Same as the closed driver.
    
    This causes a failure in GL45-CTS.compute_shader.max, which has a trivial
    bug.
