[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.
