  stop_machine: fix up ftrace.c
  stop_machine: Wean existing callers off stop_machine_run()
  stop_machine(): stop_machine_run() changed to use cpu mask
  Hotplug CPU: don't check cpu_online after take_cpu_down
  Simplify stop_machine
  stop_machine: add ALL_CPUS option
  module: fix build warning with !CONFIG_KALLSYMS
