Any restrictions on DMA address boundry?

Are there alignment restrictions on the address boundry your can
start a DMA with when using the pci_map_single() / pci_unmap_single()
calls?

For some reason, I thought they had to be cache line aligned, but when
I went back through the documentation I couldn't find any such
restriction.
