The reason is because there's a separate DT tree and all those arm drivers need DT. I have already acked EDAC patches to go through other trees too, FWIW. Which is not optimal either if someone sends fixes ontop but I cannot apply them yet because the dependent patches are in a different tree. So yes, there are at least two good reasons for merging a shared branch. -- Regards/Gruss, Boris. Good mailing practices for 400: avoid top-posting and trim the reply.
