Hi
I tried to compile a new Kernel on my iBook and get a compile Error from the
IDE PMAC Driver. I had some time to find out that "Generic PCI bus-master DMA
support" is needed to compile cleanly.
It may be better if BLK_DEV_IDEDMA_PMAC depends on BLK_DEV_IDEDMA_PCI?

This option allows the driver for the built-in IDE controller on
Power Macintoshes and PowerBooks to use DMA (direct memory access)

I think the problem is that some of the generic IDE DMA code shouldn't be
under BLK_DEV_IDEDMA_PCI ... It 's used by several non-strictly-PCI
controllers like this one. (Some non-PCI at all).
