If no one else has pulled, you should just get your local branch back to how you want it (probably by either resetting to a previous position, or by doing an interactive rebase to remove the unwanted commit), then push again to github with the -f (force) option:

git push -f  

If other people have pulled, the usual advice applies: read the recovering from upstream rebase section of the git-rebase man page to see what you're doing to the others before you do your forced update.
