2.5.60 linking error with IDE-DMA disabled

2.5.60 linking error with IDE-DMA disabled

[Guennadi Liakhovetski]

Hello

If I try to compile the kernel with IDE bus-mastering disabled (which,
IIRC, worked on 2.4.x), I get the following error:

  	ld -m elf_i386 -e stext -T arch/i386/vmlinux.lds.s

Looks like the 2.5 makefile is broken. If you didnt include any IDE DMA
support them ide-dma.c should not have been linked into the kernel. 2.4.x
seems to get this right (though I have to fix modular IDE there yet). 
I'll have a look at the rest when I try and get 2.5.60 IDE back in sync
with the newer 2.4 code.

It isn't ide-dma.c. The error messages talk about the functions
init_dma_generic and ide_hwif_setup_dma and these are in pci/generic.c
and setup-pci.c, respectively.

These are included since he has CONFIG_BLK_DEV_IDEPCI and 
CONFIG_BLK_DEV_GENERIC enabled.
