That doesn't work unless we copy quite a lot of code. There are macros
here (in lib/iov_iter.c) that we rely on, e.g. iterate_and_advance and
friends.

Instead, I propose that we place all of the new code under an ifdef to
reduce the impact on object size if the code is unused. We'll also
improve documentation around this commit.
