I don't know, but my question is - does it matter? If the support's in
3.10.1 then what's the issue?
Usually the developers keep the code in a particular branch until they get
it stable (which  usually takes months to achieve - which if they were to
have it in a moving-target branch, would mean that their code would need
to be refactored).  Once it's stable, they can forward port it into a
newer release -- the core of the code is tested but it just needs to be
shuffled about a bit to fit into the new tree.

I plan in late August to look at 3.10 for Slackware ARM, as it involves a
massive upheval for which which I do not have the time now; but if the
RPi support is there in 3.10.1, you might as well use the 3.10 kernel.
