This hard-hangs my snb here when X starts (so probably on the very first
batch). Impressive!

I've dropped this one from -fixes. And since no one piped up that the
other w/a patches fix anything, I've moved those two I've merged already
to dinq.

Totally unrelated, I think I'll instate harsher rules for w/a patches:
1. w/a patches only go in through -fixes if they indeed fix an issue we
(or a bug reporter) can reproduce.
2. w/a patches need testcases, too. Either a register check added to i-g-t
or if it's a runtime thing, a runtime assert at a nice place (where
feasible, ofc).
3. I'll randomly stall patches to bring 2. up to par for existing
workarounds.

Cheers, Daniel
