These sections aren't accurate since the github move.
You're using "commit" in a fairly liberal way. Since we're native Git now, can we adjust the vocabulary?
Once a patch is reviewed, you can commit it in your local clone of the repository in the master branch, and use `git push` to push it to the upstream repository on GitHub. You may need to run `git pull --rebase` in case other changes have been pushed in the meantime. Note that LLVM currently has a linear-history policy, which means that merge commits are not allowed. The `llvm-project` repository on GitHub is configured to reject pushes that include merges, so make sure to use `--rebase` when you pull. Alternatively you can do once `git config --global pull.rebase true` to make it the default on your system.
