[Intel-gfx] [PATCH 0/4] v5: ILK vt-d fix, more like v3 now

[Ben Widawsky]

I think Daniel caved in and agrees that making the idle cause the GPU to
be uninterruptible was the correct approach. So this patch is pretty
much the same as v3, except it has David's new global to determine the
IOMMU status. In other words, disregard v4.
