Subject: rcu: Select IRQ_WORK from TREE_PREEMPT_RCU
X-Git-Tag: v3.12-rc1~170^2^2^2~2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5361471437a97cf493c2aa7d881bbedc9c248415;p=pandora-kernel.git

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.
