Really cool, thanks for doing this, Baolu! I am currently running some
tests on this series to make sure there are no build breakages. And I
agree with Jason that:

	iommu: Use right way to retrieve iommu_ops and
	iommu: Use dev_iommu_ops() helper

can be combined into one patch. Splitting iommu_ops was something I have
been thinking about for some time, so thanks again for doing this.
