commit eec17ba9f049 ("dma-mapping: consolidate dma_supported") has removed dma_supported() from individual arch files to asm-generic/dma-mapping-common.h or if arch has its own implementation then we need to set the flag HAVE_ARCH_DMA_SUPPORTED. Otherwise we were getting error like: error: redefinition of 'dma_supported' while building with allmodconfig.
