the following bitkeeper commit (by the way of the historic.git tree):

[PATCH] DMA: Fill gaping hole in DMA API interfaces.
From: "David S. Miller" <[email protected]>
The commit does not explain why we'd need the memory barrier on ia64,
it never included the swiotlb or SGI IOMMU based platforms, and also
failed to address the map/unmap parts of the dma mapping interface,
which should provide the same ordering semantics and actually are
commonly used. The conclusion of this is that they were added in
error and should be removed.
