 A set of scheduler fixes:
 
  - Plug a load average accounting race which was introduced with a recent
    optimization casing load average to show bogus numbers.
 
  - Fix the rseq CPU id initialization for new tasks. sched_fork() does not
    update the rseq CPU id so the id is the stale id of the parent task,
    which can cause user space data corruption.
 
  - Handle a 0 return value of task_h_load() correctly in the load balancer,
    which does not decrease imbalance and therefore pulls until the maximum
    number of loops is reached, which might be all tasks just created by a
    fork bomb.
