rcu: fix _oddness handling of verbose stall warnings
CONFIG_RCU_CPU_STALL_VERBOSE depends on CONFIG_TREE_PREEMPT_RCU, but rcu_bootup_announce_oddness() complains if CONFIG_RCU_CPU_STALL_VERBOSE is not set even in the case of CONFIG_TREE_RCU. This commit therefore fixes rcu_bootup_announce_oddness() to avoid insisting on impossibilities. Reported-by: Guy Martin <gmsoft@tuxicoman.be> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
