Well, there's a single *from* version, as you say that was currently
"next-20150731" (or that was the one you used). The backport git
repository is maintained in lockstep with the *from* version (although
there's usually quite a bit of wiggle room)

The result, the output of backports, will/should compile against any
kernel starting from the earliest supported, all the way up to the
*from* version, right now I think that's 3.0 until 4.1 or so.
