This is great. I''m not putting it into 3.0.3 simply because of fears
about
knock-on side effects of this patch (e.g., taking us down guest paths
we''ve
taken before).
Could you redo the patch and update the end-of-line comments? For example,
the one that says ''no DMA'' can''t be correct any more.
A brief list of the
advertised DMA modes would be good too.
