Thomas Gleixner 2711b8e2b7 x86/smpboot: Switch to hotplug core state synchronization
The new AP state tracking and synchronization mechanism in the CPU hotplug
core code allows to remove quite some x86 specific code:

  1) The AP alive synchronization based on cpumasks

  2) The decision whether an AP can be brought up again
