That's an old branch. In fact, just deleted it now, in order to avoid further
confusion.

This is the current branch: 

    gup_dma_core 

in that same git repo. It has the current set of call site conversions. 
Please note that there are a lot of conversions that are either incomplete
or likely just plain wrong, at this point, but it is sufficient to at least 
boot up and run things such as fio(1).
