Trying to build a kernel for ARC with both options CONFIG_COMPILE_TEST and CONFIG_IOMMU_IO_PGTABLE_LPAE enabled (e.g. as a result of "make allyesconfig") results in the following build failure: | 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); | ^ Since IOMMU_IO_PGTABLE_LPAE depends on DMA API, io-pgtable-arm.c should include linux/dma-mapping.h. This fixes the reported failure.
