Hi Christoph, After merging the dma-mapping tree, today's linux-next build (arm multi_v7_defconfig) produced this warning:
drivers/base/dma-coherent.c: In function '__dma_alloc_from_coherent':
drivers/base/dma-coherent.c:160:6: warning: unused variable 'dma_memory_map'
[-Wunused-variable]
int dma_memory_map;
^
Introduced by commit
2436bdcda53f ("dma-coherent: remove the DMA_MEMORY_MAP and DMA_MEMORY_IO
flags")

Cheers,
