CC drivers/iommu/io-pgtable-arm.o linux/drivers/iommu/io-pgtable-arm.c: In function ‘__arm_lpae_alloc_pages’: linux/drivers/iommu/io-pgtable-arm.c:221:3: error: implicit declaration of function ‘dma_map_single’ [-Werror=implicit-function-declaration] dma = dma_map_single(dev, pages, size, DMA_TO_DEVICE); ^ linux/drivers/iommu/io-pgtable-arm.c:221:42: error: ‘DMA_TO_DEVICE’ undeclared (first use in this function) dma = dma_map_single(dev, pages, size, DMA_TO_DEVICE); ^ ---------------->8---------------- and so on. IOMMU_IO_PGTABLE_LPAE depends on DMA API. So io-pgtable-arm.c should include linux/dma-mapping.h.
