I've spent 30 minutes looking through your submission to find something wrong with it now, but it all looks fine, the only criticism would be that some of the changelogs could provide a little more background.
The original implementation seems odd in some places, but your new version resolves the few concerns I had (like mixing up phys and dma addresses), and I didn't see anything that should change behavior.
I hope that helps.
