1-3 are Reviewed-by: Matt Turner <matts...@gmail.com> 2+3 should be squashed together. Part of 4 looks like it should be a separate commit. Haven't reviewed 5, but should probably squash 5+6. 7 is Reviewed-by: Matt Turner <matts...@gmail.com> 8 - should split the DCE hunk into a separate patch. 9 is Reviewed-by: Matt Turner <matts...@gmail.com> _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
