You only Cced me on this particular patch, which means I have absolutely no idea what kmap_thread and kunmap_thread actually do, and thus can't provide an informed review.
That being said I think your life would be a lot easier if you add helpers for the above code sequence and its counterpart that copies to a potential hughmem page first, as that hides the implementation details from most users.
