Subject: AMR: sun7i: CPU hotplug support?

Hi,

did anyone already happen to look into enabling CPU hotplug for the
Allwinner A20 in upstream? I'm currently running the sunxi-next branch
on Banana Pi, and echo 0 > .../cpu1/online just hangs the system. The
old 3.4 LeMaker kernel works fine in this regard. I can try to look into
details and port things over, just want to avoid duplicate efforts.

Thanks,
Jan
