I know - I've made the same set of changes to a kernel tree I have.
(IIRC There are some bugs in the branch, it is also well out of date.)

Unfortunately that tree has some other (unrelated) changes so I can't
just commit it!

Most of the changes are to code that references the fields - so are
mechanical.
