The patches may effectively apply against a 3.6 kernel but who is going to embed a such kernel on an Armada-based board ? IMO, stabilize the Armada support for kernels older than 3.10 is a waste of time, for you, for the -stable maintainers and for me. Some important features (for Armada SoCs) are missing on this kernels. Then I don't think that someone is going to use a kernel older than 3.10 with an Armada-based board. But anyway, it is not up to me and I have hopefully added all the needed -stable informations to the v3 patch series. Simon
