This is with your patch applied on top of linux-2.6.32.1.tar.gz no other patches or additions .
OK , it looks like I wandered right by the first file ie: 'kernel/rcutree.h' so I need to patch that as well . Doing this by hand as the offending system is not online and all I have is serial console access presently . But , the last two you've changed to 'void __init' instead of just 'void' . Do you want me to add those changes to the file 'kernel/rcutree_plugin.h' as well ?
# grep rcu_bootup_announce kernel/rcu* kernel/rcutree.c: rcu_bootup_announce(); kernel/rcutree.h:static inline void rcu_bootup_announce(void); kernel/rcutree_plugin.h:static void rcu_bootup_announce(void) kernel/rcutree_plugin.h:static void rcu_bootup_announce(void)
