FWIW debug_dma_dump_mappings() is also called by the Intel VT-d driver, but

I'll update the changelog.
This does rather beg the question of
whether it's right to have bits of low-level dma-debug internals *only*
called by a couple of IOMMU drivers, but that can wait for another day.
My gut feeling is that it is wrong, but I didn't have time to look into
the details and history of how this happened.
