Hi all,

This is v2 of __private.

Link for v1: http://marc.info/?l=linux-sparse&m=144988906932520&w=2

Change since v1:

*	#undef __irqd_to_state after used (Peter Zijlstra)


This patchset introduces a __private modifier for sparse to detect misuses of
private members of structs. This could make maintenace a little easier and
prevent some potential bugs.


This patchset consists of three patches:

1.	Introduce __private and related macro, also improve compiler.h a litte
	bit

2.	Privatize rcu_node::lock

3.	Privatize irq_common_data::state_use_accessors

This patchset is against

	-rcu/rcu/next	c95a158356397844a5a6deb0bd58758084f891df

because it depends on commits:
	
	"rcu: Create transitive rnp->lock acquisition functions"
and
	"rcu: Add transitivity to remaining rcu_node ->lock acquisitions


Tested by 0day.

Looking forward to any suggestion, question and comment ;-)

Regards,
Boqun
