Hi Stephen,

Just following back on this.

I've changed the few other things you spotted, but this one making the
timer unusable.

I think what happens here is that we have the A31 I've tested these
patches on is a quad-core SoC. As such, the device tree has 4 CPUs
declared. However, we don't have any SMP support for it now. So we end
up having 4 cpus set as possible, and only one online (the boot cpu),
which isn't working.

Would using cpu_online_mask work in our case?

Thanks,
Maxime
