Paul E. McKenney	3808dc9fab	rcutorture: Abstract torture_shuffle() ... The torture_shuffle() function forces each CPU in turn to go idle periodically in order to check for problems interacting with per-CPU variables and with dyntick-idle mode. Because this sort of debugging is not specific to RCU, this commit abstracts that functionality. This in turn requires abstracting some additional infrastructure. Signed-off-by: Paul E.

Paul E. McKenney	f67a33561e	rcutorture: Abstract torture_shutdown_absorb() ... Because handling races between rmmod and normal shutdown is not specific to rcutorture, this commit renames rcutorture_shutdown_absorb() to torture_shutdown_absorb() and pulls it out into then kernel/torture.c module. This implies pulling the fullstop mechanism into kernel/torture.c as well. The exporting of fullstop and fullstop_mutex is ugly and must die. And it does in fact die in later commits that introduce higher-level APIs that encapsulate both of these variables. Signed-off-by: Paul E.

Paul E. McKenney	51b1130eb5	rcutorture: Abstract rcu_torture_random() ... Because rcu_torture_random() will be used by the locking equivalent to rcutorture, pull it out into its own module. This new module cannot be separately configured, instead, use the Kconfig "select" statement from the Kconfig options of tests depending on it.
