There are two problems with this series:

1) It doesn't compile if CONFIG_HOTPLUG_CPU isn't enabled. Please also
make sure that Tegra20-only and Tegra30-only kernels compile (I didn't
check this, so it may well already be the case).

2) It prevents the "reboot" from working; the kernel hangs as it
attempts to do the reboot. I've confirmed this isn't the case without
this patch series, even if CONFIG_HOTPLUG_CPU is enabled.

I assume we'll want to enable CONFIG_HOTPLUG_CPU in tegra_defconfig once
this is checked in?
