hehe, granted there might be other conditions, but for PCI DMA mapping
specifically, it is (unfortunately) currently defined to not fail.
That wants changing for ppc64 and x86-64 iommu, which are a -lot- more
likely to fail an iommu transaction than parisc or sparc64... but that's
the way it is for now. Way too many drivers assume PCI DMA mapping
always succeeds.
