[PATCH v5 0/5] ARM: rockchip: add smp functionality

[heiko@sntech.de (Heiko Stübner)]

gaah, there I just learned about the arm at kernel.org address and still didn't 
remember when digging up this old recipient list - which of course resulted in 
Kevin not being included.

Additionally I also had the old devicetree list included.

So I'll do it again shortly :-)


Sorry for the noise
