That's currently sitting in Darrick's iomap tree, commit 908a1ad89466
"iov_iter: Handle compound highmem pages in copy_page_from_iter_atomic()"

It's based on 6.5-rc3, so it would be entirely possible for Darrick
to send Linus a pull request for 908a1ad89466 ... or you could pull
in 908a1ad89466.  I'll talk to Darrick tomorrow.
