You can start by using
  git log --cherry-pick ....
which compares commits based on their patch contents, not just the SHA1.

You can use a moving tag (say APPLIED) to keep track of till what point
on master you have done the necessary cherry-picks, and then something like
this may work for you:
  git log --cherry-pick release..master ^APPLIED
