    Pull scheduler changes from Ingo Molnar:
     "The main changes in this cycle were:
    
       - sched/fair load tracking fixes and cleanups (Byungchul Park)
    
       - Make load tracking frequency scale invariant (Dietmar Eggemann)
    
       - sched/deadline updates (Juri Lelli)
    
       - stop machine fixes, cleanups and enhancements for bugs triggered by
         CPU hotplug stress testing (Oleg Nesterov)
    
       - scheduler preemption code rework: remove PREEMPT_ACTIVE and related
         cleanups (Peter Zijlstra)
    
       - Rework the sched_info::run_delay code to fix races (Peter Zijlstra)
    
       - Optimize per entity utilization tracking (Peter Zijlstra)
    
       - ... misc other fixes, cleanups and smaller updates"

### Now generating an X.509 key pair to be used for signing modules.

### If this takes a long time, you might wish to run rngd in the
### background to keep the supply of entropy topped up.  It
### needs to be run as root, and uses a hardware random
### number generator if one is available.
