[PATCH tip/core/rcu 07/12] rcu: Move rcu_{expedited,normal} definitions into rcupdate.h

[paulmck@kernel.org]

From: Ben Dooks <ben.dooks@codethink.co.uk>

This commit moves the rcu_{expedited,normal} definitions from
kernel/rcu/update.c to include/linux/rcupdate.h to make sure they are
in sync, and also to avoid the following warning from sparse:

kernel/ksysfs.c:150:5: warning: symbol 'rcu_expedited' was not declared. Should it be static?
kernel/ksysfs.c:167:5: warning: symbol 'rcu_normal' was not declared. Should it be static?
