This series provides torture-test updates. 1. Use gawk instead of awk for systime() function. 2. Dispense with Dracut for initrd creation. 3. Handle jitter for CPUs that cannot be offlined. 4. Handle systems lacking the mpstat command. 5. Add worst-case call_rcu() forward-progress results. 6. Pull callback forward-progress data into rcu_fwd struct. 7. Thread rcu_fwd pointer through forward-progress functions. 8. Move to dynamic initialization of rcu_fwds. 9. Complete threading rcu_fwd pointers through functions. 10. Dynamically allocate rcu_fwds structure. 11. Allow "CFLIST" to specify default list of scenarios. 12. Hoist calls to lscpu to higher-level kvm.sh script.
