Hi, One of my colleagues has issues with 3.1.0: it can't find dma_common_get_sgtable. HAVE_GENERIC_DMA_COHERENT is set, and hence BPAUTO_BUILD_DMA_SHARED_HELPERS is not set. Because of that, dma_common_get_sgtable isn't defined. Sorry for the stupid question, but I can't think on how dma_common_get_sgtable should be declared on 3.1 since it doesn't exist in the base kernel obviously. Maybe that helper is supposed to be used only in code that should be under ifdef? thanks...
