The kbuild bot should generally pick up any branch on git.kernel.org,
and the patches sent to the mailing list. It tests a lot of things
configurations, but I tend to find some things that it doesn't find
by doing lots of randconfig builds on fewer target architectures
(I only build arm, arm64 and x86 regularly).

I remember that there was some discussion about a method
to get the bot to test other branches (besides asking Fengguang
to add it manually), but I don't remember what came out of that.
