Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: NAlexey Dobriyan <adobriyan@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Move the dmaengine subsystem up early in the drivers Makefile so DMA is made available early to all drivers, just like e.g. regulators. Now even regulators can use DMA on the same initlevel. As a result we can bump the ste_dma40 and coh901318 dmaengine drivers down one initlevel to subsys_init().
