ARM: DMA-mapping: fix memory leak in IOMMU dma-mapping implementation This patch removes page_address() usage in IOMMU-aware dma-mapping implementation and replaced it with direct use of the cpu virtual address provided by the caller. page_address() returned incorrect address for pages remapped in atomic pool, what caused memory leak.
