Hmmm.... Yes. Could you please execute the following command from the top-level directory of your patched kernel source tree?
grep rcu_bootup_announce kernel/rcu*
I would expect the following output:
kernel/rcutree.c: rcu_bootup_announce(); kernel/rcutree.h:static void rcu_bootup_announce(void); kernel/rcutree_plugin.h:static void __init rcu_bootup_announce(void) kernel/rcutree_plugin.h:static void __init rcu_bootup_announce(void)
Thanx, Paul
