I think you missed the part about squashing your changes together
into the first commit of the topic.  I just rewrote the topic
to do that.  Now you can start working from commit 5922fc2c:

 git checkout -b tmp 5922fc2c
 git rm Help/policy/CMP0054.rst Help/release/dev/if-sanity.rst
 git checkout HEAD~1 -- Help
 git rm -rf Tests/RunCMake/CMP0054
 git checkout HEAD~1 -- Tests/RunCMake/CMakeLists.txt
 git commit --amend

Then keep editing the files and amending the commit to leave
behind only the refactoring pieces.  Amend the commit message
accordingly too.  Then do:

 commit=$(git commit-tree 5922fc2c^{tree} -p HEAD)
 git merge $commit
 git commit --amend -C 5922fc2c

to restore the rest of the commit's changes.  Then rebase
the rest of the topic to get the warning cleanups.
