Well, if you want to push it through fixes (I don't think it's too late
yet for such games) I agree that we want to keep around the spinning
workaround with a module option.

As Chris pointed out when submitting his rfc patch, we've now scored
missed irq issues on ivb, snb and some gen3 chips. So it looks like this
would be generally useful infrastructure. But in the case that we keep it
I have some pending review-comments on what's currently in ... ;-)
