I would like to get these patches into the master branch soon. I assume
that there are still some problems in there, but as long as it does not
hurt the other kernel versions, I think it is ok. If someone sees
problematic code please report that.

This is my plan:
1. Test if these changes break anything with kernel 4.9 and 4.4
2. Fix the problems found in 1. and also other problems reported by
people and merge this around the end of the weekend.

We should *not* migrate all targets to kernel 4.14 for the next release,
but for some targets where most of the development is happening in the
mainline kernel it would be nice to have kernel 4.14. This would be x86
and some arm/arm64 targets.

For the sunxi target it would be nice to have kernel 4.14 support and I
have two unsupported arm64 boards with Marvell and Rockchip SoCs which
are supported in mainline kernel 4.14, but not so well in kernel 4.9.

Are there any comments on this plan?
