intel-iommu: Performance improvement for dma_pte_clear_range() It's a bit silly to repeatedly call domain_flush_cache() for each PTE individually, as we clear it. Instead, batch them up and flush a whole range at a time. We might as well refrain from recalculating the PTE address from scratch each time round the loop too.
