FWIW with the below patch I don't see any "screwed shadow mapping"
warnings on my board, and still later see a tonne of KASAN splats in the
scheduler.

It is possible that I missed something, but I think it means that
shadow is alright.

I wonder whether this happens on 4.4. If not, than something in
4.5-rc1 caused this, and the obvious suspect here is irq stack.

It doesn't seem to happen on 4.4, it starts somewhere before 4.5-rc1. I
tested the arm64 branch that we pushed upstream with the irq stack
changes but it didn't trigger. It could as well be a combination of
multiple change or just something else.

We'll do some bisecting, though it's not that fun going through the
merging window commits, especially since many are based on 4.4-rcX (we
could try on merges only first, there are fewer).
