In my 4.8 kernel, I built the backporting environment by using tag "v4.14-rc4-1". When I used that Python script to generate backport tree, got an error: ./gentree.py --verbose --clean --git-revision master --copy-list copy-list.ath ../linux-4.9 ../backports-output Get original source files from git ...

So if you use v4.14-rc4-1 tag you can only use v4.14 kernel source to generate the backports package. But backports list can help you better: https://backports.wiki.kernel.org/index.php/Mailing_list Ah, but I see from the archives that you asked there already.
you can also use the backports tree from openwrt. as far as i know the official backports tree is broken on many points so you need to manually edit alot of things to get it to work. backports tree provided by openwrt did already take care of it i once did my own backports version and it was alot of work of manually editing to get all to work
