Generally when we do kernel fixes for gpu hangs like that we don't add
parameters (would drown in them otherwise) but simply queue it up to
-fixes and slap a cc: stable on it. Gpu hang fixes are critical enough
imo for that treatment, even when it's for brand new userspace code.
Any specific reason why we shouldn't follow this approach here? I'd
make the patch simpler and we could dump a bit of userspace code, too.
