Sometimes I can be useful to download a changes contained in a Github pull request as a unified diff. It turns out to be very easy. To view a commit as a diff/patch file, just add .diff or .patch to the end of the URL For instance
Today I needed to rebase my etnaviv fork to the current master of upstream. I need to say that I never did this before but with git this is a breeze. View the code on [Gist](https://gist.github.com/austriancoder/724a0a8d1db4f229e197d501f8b49fa5).If you get a merge conflict during rebase, you only need to follow the instructions git gives you.
