Overall idea:
Detect lockups by watching for timeouts (vm flush / fence), return -EIOs,
handle them at ioctl level, reset the GPU and repeat last ioctl.
GPU reset is done by doing suspend / resume cycle with few tweaks:
- CPU-only bo eviction
- ignoring vm flush / fence timeouts
- shortening waits

Martin,
I'm wondering how below patch (which builds upon the above) affects
reclocking stability. I can't test it on my card, because it has only
one performance level. Can you test it on yours?
Hi Marcin,
I was away from my computers for a few days. I'll test this patch tonight.
Martin
