Alex Williamson bd13969b95 iommu: Split iommu_unmaps ... iommu_map splits requests into pages that the iommu driver reports that it can handle. The iommu_unmap path does not do the same. This can cause problems not only from callers that might expect the same behavior as the map path, but even from the failure path of iommu_map, should it fail at a point where it has mapped and needs to unwind a set of pages that the iommu driver cannot handle directly. amd_iommu, for example, will BUG_ON if asked to unmap a non power of 2 size. Fix this by extracting and generalizing the sizing code from the iommu_map path and use it for both map and unmap.
