Hmm, I see new early crashes with that patch here in some cases unfortunately:

PANIC: early exception 06 rip 10:ffffffff8082df2d error 0 cr2 0

Not sure what's going wrong. I think the patch is correct, but there
are probably more bugs around triggered by some change. Perhaps it is
better to just revert Jeremy's patch (789bad4ca2b604f2f21ae7e3d64b67325ec8f9bb) for now.
