Hi, all.

This is small patch series for ARM32 which needed to be able to bring
secondary CPUs up not only during the initial boot, but at runtime also.
For example, during CPU hotplug.

OOI, we don't have CPU hotplug in Xen at the moment. So do you have CPU hotplug patch coming up?

No, I don't. These patches are result of my playing with PSCI). I just wanted to be sure that second CPU_ON request would properly bring CPU up again after performing CPU_OFF request. For that reason, I just hacked Xen to issue cpu_up()/cpu_down() by pressing a key. So this is definitely not for upstream)
