Ah, nice, a port to a more recent kernel. Do you also have a queue according to 
our noarch / arch split? Would enable reuse for other archs.

Actually, we haven't tested 32-bit even on 4.4 in a while.

Cool! This is a valuable step forward /wrt CI. How long do these builds run 
each, roughly? We scale by spawning a separate build per kernel, right?

I had travis on the to-do list for a while, but everyone around lacked time to 
finish what we started internally. I'll dig out what we had to ensure we can 
merge valuable ideas. But that may even happen after creating a baseline with this.
