I just merged Marc's smp_ops branch below into above branch, and built
a kernel from there with vexpress and imx support together.

 git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git smp_ops-v3.5-rc2

The kernel boots fine on both imx5 and imx6, and I did not notice any
obvious feature breaking \o/
