How to force a push to succeed?

[Jeffrey Walton]

I tested some changes that lead to a dead end. The changes need to be
removed. The changes were added in 7 commits.

I went back in time to the point before the changes:

    $ git reset --hard HEAD~7
    HEAD is now at 559fc3b Fix benchmark selection code (GH #464)

When I attempted to push:

    $ git push
    Username for 'https://github.com': noloader
    To https://github.com/noloader/cryptopp.git
     ! [rejected]        master -> master (non-fast-forward)

I tried to commit, but Git claims there's nothing to add:

    $ git commit
    On branch master
    Your branch is behind 'origin/master' by 7 commits, and can be
fast-forwarded.

Commit seems to be the wrong command as Git appears to be trying to do
something I don't want.

How do I force the push to succeed?

Thanks in advance.
