s/the // ?  (note that this is used in quite a few places)

Can you use up the full 80 characters for your text?  As-is it reads a
little odd due to the very short lines.

The other thing that strikes me as odd is the placement in the core-api
directory together with other drivers-facing documentation.  Swiotlb
is internal to the dma-mapping subsystem and not really what is a core
API.  I don't really know where else it should be placed, though - nor
do I really understand the "modern" hierarchy in Documentation, but maybe
Jon has a good idea?

Except for these nitpicks the documentation looks good to me, thanks
a lot!
