Install the callbacks via the state machine and let the core invoke the callbacks on the already online CPUs. The smp_call_function_single() is dropped because the ONLINE callback is invoked on the target CPU since commit 1cf4f629 ("cpu/hotplug: Move online calls to hotplugged cpu"). smp_call_function_single() invokes the invoked function with interrupts disabled, but this calling convention is not preserved as the MSR is not modified by anything else than this code.
