If I was to guess; because Windows allocates MMIO space differently it
hasn't been a problem.
Which begs the question; does Ilpo's series improve things enough that
we wouldn't have these problems either?
Maybe we should just tail my patches on Ilpos' series and then land them
linux-next the very beginning of next cycle and beg everyone who was
affected to test linux-next.
