Using __CPUINIT instead of __INIT puts the secondary CPU startup code into the "right" section: it will not be freed in hotplug configurations, allowing hot-add of cpus, while still getting freed in non-hotplug configs. Tested successfully on Fast-Models and on Arndale for VCPU hotplug.
not quite sure how testing on Arndale verifies this change?

Otherwise looks ok to me (not guaranteeing that cpu hotplug will magically work for KVM using this change though). -Christoffer
