[PATCH tip/core/rcu 77/88] rcu: Remove #ifdef moving rcu_end_inkernel_boot from rcupdate.h

From: Paul E. McKenney
Date: Thu May 25 2017 - 18:07:26 EST


This commit removes a #ifdef and saves a few lines of code by moving
the rcu_end_inkernel_boot() function from include/linux/rcupdate.h to
include/linux/rcutiny.h (for TINY_RCU) and to include/linux/rcutree.h
(for TREE_RCU).
