drivers/built-in.o(.text+0x39f90): In function `init_dma_generic':
drivers/ide/pci/generic.c:77: undefined reference to `ide_setup_dma'
drivers/built-in.o(.text+0x4a7e8): In function `ide_hwif_setup_dma':
drivers/ide/setup-pci.c:511: undefined reference to `ide_setup_dma'

Even if it is stubbed correctly though, don't we want DMA (i.e. it's 
safe) with most of those drivers?
