[yocto] [raspberrypi] raspi3 vs raspi2

I've never tried with 4.8, but I sent patches to the list that add 64 bits support for 4.7.10 - and this one, I tested and it is working.
It's probably possible to port 64 bits to 4.4 as well, but I'm not sure if it's worth the effort.
I have 4.7 covered, there is some "built-in" level of support in 4.8 (but I don't know what's working or not there), and I'll sure work it for 4.9 soon.

Yes, my conf/local.conf contains:
PREFERRED_VERSION_linux-raspberrypi = "4.8%"
If you clone git://github.com/raspberrypi/linux.git and checkout the 4.8.y branch, you'll see that there's no commit
ea6eeaff07c4881e6287fe3e7ea58fc30e5569d7 anywhere in that branch. In fact there is no such commit anywhere in that repository:
$ git branch --contains ea6eeaff07c4881e6287fe3e7ea58fc30e5569d7
error: no such commit ea6eeaff07c4881e6287fe3e7ea58fc30e5569d7
