    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.
