Install the callbacks via the state machine and let the core invoke
the callbacks on the already online CPUs.  

This is causing an oops on ppc64le QEMU, looks like a NULL
pointer:  

Did you tested it against tip WIP.hotplug?

I noticed tip started failing in my CI environment which tests on QEMU.
The failure bisected to commit 425209e0abaf2c6e3a90ce4fedb935c10652bf80

That's very useful, thanks Anton!

I have removed this commit from the series for the time being, refactored the 
followup commits (there was one trivial conflict). We can re-try this patch when a 
fix is found.

Thanks,

	Ingo
