CI grabs patches from patchwork and tries to apply them to one of the three
bases: mm-unstable, mm-new or the latest Linus' commit merged into mm.git.

If patches apply, the other bases are not checked. 

This patches applied cleanly to mm-unstable and successfully passed (at
least once :) )

I can't say that CI I run has a great coverage. I don't know what coverage
mm-new has though.
