backport of Christian's patch

I tried backporting Christian's patch from
https://bugs.freedesktop.org/show_bug.cgi?id=54129#c11 but it did not help
either. I suppose the following /sys/kernel/debug/dri/0/radeon_fence_info
output indicates that the patch took effect, since the emitted numbers are
above 0x100000000LL?
