I would like to. I am currently stuck trying to figure out which commits 
in the archlinux tree refer to the lts release version. Sadly the 
versions are build from different sources. LTS from tarball from 
kernel.org and mainline from there own fork of linus tree. So the commit 
hashes are different and I can not easily figure out the good commit to 
start from.

Kind regards,
Felix
