Thomas Gleixner 5475abbde7 x86/smpboot: Remove the CPU0 hotplug kludge ... This was introduced with commit e1c467e690 ("x86, hotplug: Wake up CPU0 via NMI instead of INIT, SIPI, SIPI") to eventually support physical hotplug of CPU0: "We'll change this code in the future to wake up hard offlined CPU0 if real platform and request are available." 11 years later this has not happened and physical hotplug is not officially supported. Remove the cruft.
