rcu: Remove *_SLOW_* Kconfig options
The RCU_TORTURE_TEST_SLOW_PREINIT, RCU_TORTURE_TEST_SLOW_PREINIT_DELAY, RCU_TORTURE_TEST_SLOW_PREINIT_DELAY, RCU_TORTURE_TEST_SLOW_INIT, RCU_TORTURE_TEST_SLOW_INIT_DELAY, RCU_TORTURE_TEST_SLOW_CLEANUP, and RCU_TORTURE_TEST_SLOW_CLEANUP_DELAY Kconfig options are only useful for torture testing, and there are the rcutree.gp_cleanup_delay, rcutree.gp_init_delay, and rcutree.gp_preinit_delay kernel boot parameters that rcutorture can use instead. The effect of these parameters is to artificially slow down grace period initialization and cleanup in order to make some types of race conditions happen more often.
This commit therefore simplifies Tree RCU a bit by removing the Kconfig options and adding the corresponding kernel parameters to rcutorture's .boot files instead. However, this commit also leaves out the kernel parameters for TREE02, TREE04, and TREE07 in order to have about the same number of tests slowed as not slowed. TREE01, TREE03, TREE05, and TREE06 are slowed, and the rest are not slowed.

The CONFIG_RCU_CPU_STALL_VERBOSE Kconfig parameter causes preemptible RCU's CPU stall warnings to dump out any preempted tasks that are blocking the current RCU grace period. This information is useful, and the default has been CONFIG_RCU_CPU_STALL_VERBOSE=y for some years. It is therefore time for this commit to remove this Kconfig parameter, so that future kernel builds will always act as if CONFIG_RCU_CPU_STALL_VERBOSE=y.

rcu: Remove *_SLOW_* Kconfig options The RCU_TORTURE_TEST_SLOW_PREINIT, RCU_TORTURE_TEST_SLOW_PREINIT_DELAY, RCU_TORTURE_TEST_SLOW_PREINIT_DELAY, RCU_TORTURE_TEST_SLOW_INIT, RCU_TORTURE_TEST_SLOW_INIT_DELAY, RCU_TORTURE_TEST_SLOW_CLEANUP, and RCU_TORTURE_TEST_SLOW_CLEANUP_DELAY Kconfig options are only useful for torture testing, and there are the rcutree.gp_cleanup_delay, rcutree.gp_init_delay, and rcutree.gp_preinit_delay kernel boot parameters that rcutorture can use instead. The effect of these parameters is to artificially slow down grace period initialization and cleanup in order to make some types of race conditions happen more often. This commit therefore simplifies Tree RCU a bit by removing the Kconfig options and adding the corresponding kernel parameters to rcutorture's .boot files instead. However, this commit also leaves out the kernel parameters for TREE02, TREE04, and TREE07 in order to have about the same number of tests slowed as not slowed. TREE01, TREE03, TREE05, and TREE06 are slowed, and the rest are not slowed. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
