 Log Message:
 - Avoid the race with CPU online/offline state changes, when setting the
   affinity (cpu_lock protects these operations now).
 - Disallow setting of state of CPU to to offline, if there are bound LWPs,
   which have no CPU to migrate.
 - Disallow setting of affinity for the LWP(s), if all CPUs in the dynamic
   CPU-set are offline.
 - sched_setaffinity: fix invalid check of kcpuset_isset().
 - Rename cpu_setonline() to cpu_setstate().
 
 Should fix PR/39349.
