The bisect (which took me quite some time) points at commit 98ec77397a5c
("drm/i915: Make primary_enabled match the actual hardware state"). The
bisect log is pasted at the end of this message.
Commit 98ec77397a5c reverts cleanly on top of v3.16-rc4. Booting
v3.16-rc4 with that revert added makes the WARNING go away. But note
that I have no idea whether that revert actually is a proper fix here.
Feel free to prod me for further testing, etc.
