Hello!

This series contains torture-test updates:

1.      Use correct locking primitive, thus avoiding deadlock, courtesy
        of Alexey Kodanev.

2.      Exchange TREE03 and TREE04 geometries in order to improve bug-location
        rates.

3.      Exchange TREE03 and TREE08 NR_CPUS, speed up CPU hotplug to further
        improve bug-location rates.

4.      Allow negative values of nreaders to in order to oversubscribe
        the CPUs, again to improve bug-location rates.

5.      Change longdelay_us to longdelay_ms in order to better reflect
        reality.  (Not that gcc cares, but people reading the code just
        might.)

6.      Replace open-coded memory barriers with the shiny new
        smp_store_release() and smp_load_acquire() primitives.

7.      Test SRCU cleanup code path in order to improve test coverage.

8.      Avoid explicitly setting CONFIG_TASKS_RCU, given that it is
        now set implicitly based on other configuration options.

9.      Update configuration fragments from CONFIG_RCU_FANOUT_EXACT to
        the new rcutree.rcu_fanout_exact= boot parameter.

10.     Make rcutorture scripts force RCU_EXPERT so that they can still
        build the needed kernel configurations.

11.     Update TREE_RCU-kconfig.txt to describe new kernel-parameter
        setup.

12.     Make torture scripts display "make oldconfig" errors

13.     Allow repetition factors in Kconfig-fragment lists.  Because
        typing 48 repetitions of "TINY02" is getting old.

                                                        Thanx, Paul
