iommu/io-pgtable-arm: Fix io-pgtable-arm build failure
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.
