Yes, I've pulled from Linus master into olpc-kernel master, then
created branch olpc-4.1 and applied my first patch.
http://dev.laptop.org/git/olpc-kernel/
http://dev.laptop.org/git/olpc-kernel/commit/?h=olpc-4.1&id=48f0337b26e80b6fe5df63daf2165af435698000
Added you to group for access to olpc-kernel.
Repository path is crank.laptop.org:/git/olpc-kernel

Yes, there's a siv121c camera in x86-3.3 that will have to be
ported; and maybe upstreamed, though it is an ugly copy. ;-)

4.1rc5 is now olpc-4.1 on olpc-kernel. Can't speak for F-22.

Even more awesome, some of these are probably missing or changed
kernel options. Some of those kernel bits have changed a lot upstream.

Do we have a 4.1 branch in the olpc-kernel git repo yet? Is it worth
it or would it be worthwhile me setting up one against the Fedora
upstream to allow us to more easily work there, rebase etc?

Can we setup a git branch sooner rather than later as a central place
to pull the latest and greatest from.

Happy to help there. We likely need to rebase a few patches for camera
modules etc from the older branches, happy to help there where
possible.

I've got a possible route for the 1.75 as mentioned above, once we get
a 4.1 branch I can add that and see how much further on we can get
with that. XO-4 on the other hand, as you mention, is a massive job!

Re: [Server-devel] Two (minimal) goals for a kernel for XO1.5 based upon fc22?
The v4.1-rc5 kernel boots fine on XO-1.5, though there are a few
things to be fixed; screen blanks on boot, camera LED stays on and
camera doesn't work, temperature of CPU is not accessible, and suspend
fails to complete. Some of these probably my haste.
This meets George's requirements.
The patch relative to v4.1-rc5:
http://dev.laptop.org/~quozl/y/1YxsfX.txt
The boot dmesg:
http://dev.laptop.org/~quozl/z/1Yxsg9.txt
You might take your favourite Fedora 22 kernel, apply that patch,
fixing any conflicts, reconfigure the kernel, and build.
Or you might compare the xo_1.5_defconfig against the Fedora 22 kernel
.config.
If you guys can help test and fix these apparently minor problems,
then I can pull upstream into olpc-kernel repository and make a later
branch.
Chances are it would work fine with XO-1 too, with a bit of
configuration merging.
However, this doesn't help with XO-1.75 and XO-4, which are still just
as large a job as they ever were. ;-{ x86 is so easy.
