I'm dropping stable CC (for now), as I'm not sure I completely understood the process for inclusion in stable trees. Do I have to wait for the patch to be on Linus' tree before CCing stable?
As for the link which this patch fixes, you mean aa7eb2bb4e4a22e41bbe4612ff46e5885b13c33e (arm: zynq: Add smp support)? where you added SMP support for zynq.
Thanks, Luis Araneda.
