Subject: [PATCH tip/core/rcu 0/2] Debloat rcu_segcblist header file

Hello!

This series debloats the include/linux/rcu_segcblist.h include file:

1.	Leave data structures in include/linux/rcu_segcblist.h, but
	move functions to kernel/rcu/rcu_segcblist.h, courtesy of
	Ingo Molnar.

2.	Move non-trivial functions from kernel/rcu/rcu_segcblist.h
	to kernel/rcu/rcu_segcblist.c to avoid excessive inlining
	of large functions.

Additional patches open-coding some of the more trivial functions to follow.

							Thanx, Paul
