McKenney <paulmck@xxxxxxxxxxxxxxxxxx> CommitDate: Sun, 18 Aug 2013 17:40:25 -0700 rcu: Select IRQ_WORK from TREE_PREEMPT_RCU TREE_RCU and TREE_PREEMPT_RCU both cause kernel/rcutree.c to be built, but only TREE_RCU selects IRQ_WORK, which can result in an undefined reference to irq_work_queue for some (random) configs: kernel/built-in.o In function `rcu_start_gp_advanced': kernel/rcutree.c:1564: undefined reference to `irq_work_queue' Select IRQ_WORK from TREE_PREEMPT_RCU too to fix this.
