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)
