Jason Gunthorpe 1eb0ae6fbd iommupt/vtd: Support mgaw's less than a 4 level walk for first stage ... If the IOVA is limited to less than 48 the page table will be constructed with a 3 level configuration which is unsupported by hardware. Like the second stage the caller needs to pass in both the top_level an the vasz to specify a table that has more levels than required to hold the IOVA range.
