This series fixes the OOM errors. However, if I torture the kernel driver
more, I can get it to deadlock and end up with unkillable processes. I can
also get an OOM error. I just ran the test 5 times:
AMD_DEBUG=testgdsmm glxgears & AMD_DEBUG=testgdsmm glxgears &
AMD_DEBUG=testgdsmm glxgears & AMD_DEBUG=testgdsmm glxgears &
AMD_DEBUG=testgdsmm glxgears
