[PATCH 0/2] more migration vs CPU hotplug fixes

[Nathan Lynch]

Despite recent fixes, userspace-initiated CPU hotplug still can
destructively race with the migration code's CPU state manipulations
on the destination. Also, since such manipulations can consist of
mass-onlining and -offlining half or more of the CPUs in the system,
take care to reschedule when needed.

  powerpc/rtas: use device model APIs and serialization during LPM
  powerpc/rtas: allow rescheduling while changing cpu states
