But it touches vduse.  And vduse is marked broken because it still has
this long standing issues.  You don't add "ehancements" to code marked
BROKEN begfore fixing that.

Hi Christoph,

This code does not touch the DMA API at all. Actually, we could even
remove all the DMA code and these changes would work the same. Can't
we just continue with this series and remove the abuse of the DMA API
in parallel?

If you detect broken uses of the DMA API I've missed please let me
know and I'll be happy to remove or change them.

Thanks!

Before you add new features to vduse, please remove the broken abuse of
the DMA API first.  Without that no new feature work should go into
this code.
