When we use the iommu_area_alloc helper to get dma addresses we specify the boundary_size parameter but not the offset (called shift in this context). As long as the offset (start_dma) is a multiple of the boundary we're ok (on current machines start_dma always seems to be 4GB). Don't leave this to chance and specify the offset for iommu_area_alloc. Signed-off-by:
