I am attaching two logs.  I now the mailing lists will be unhappy, but
 don't want to try and spam a bunch of log through the mailing liast.
The two logs show the differences between the working and non-working
imx6q 3D accelerator when trying to run a simple glmark2-es2-drm demo.

The only change between them is the 2 line code change you suggested.

In both cases, I have cma=128M set in my bootargs.  Historically this
has been sufficient, but cma=256M has not made a difference.
