Robin Murphy f8d5496131 iommu/io-pgtable-arm: Allow appropriate DMA API use ... Currently, users of the LPAE page table code are (ab)using dma_map_page() as a means to flush page table updates for non-coherent IOMMUs. Since from the CPU's point of view, creating IOMMU page tables *is* passing DMA buffers to a device (the IOMMU's page table walker), there's little reason not to use the DMA API correctly. Allow IOMMU drivers to opt into DMA API operations for page table allocation and updates by providing their appropriate device pointer. The expectation is that an LPAE IOMMU should have a full view of system memory, so use streaming mappings to avoid unnecessary pressure on ZONE_DMA, and treat any DMA translation as a warning sign.
