This isn't actually the original purpose of CONFIG_GENERIC_ISA_DMA (it was to allow an architecture to provide ISA-like DMA without having to use the ISA DMA request/free functions - eg, they need to claim interrupts on request_dma() and free them on free_dma()).
However, since this function isn't used on ARM, it doesn't affect me, and so I don't have any problem with this patch. 8)
