[PATCH tip/core/rcu 0/11] Add debugobjects checking to RCU callbacks

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

Hello!

This patchset pulls Mathieu's debugobject-specific commits out of the
earlier patchbomb (http://lkml.org/lkml/2010/5/4/298):

1.	Add transition-check capability to debugobjects.
2.	Add init_rcu_head_on_stack() and destroy_rcu_head_on_stack() APIs.
3.	Remove rcu_head initializations from RCU, except for those
	for on-stack rcu_head structures, which must use the APIs
	introduced in #2 above.
4-9.	Ditto for powerpc, block, staging, fs, mm, and selinux.
10.	Remove the old rcu_head initialization APIs.
11.	Add the debugobjects workings to RCU, enabled by
	CONFIG_DEBUG_OBJECTS_RCU_HEAD.

These have been reordered and consolidated to reduce inter-commit
dependencies.

							Thanx, Paul
