[PATCH tip/core/rcu 0/28] patches queued for 3.1, first installment

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

Hello!

This patchset contains some simplifications, bug fixes, documentation
updates, and a bunch of leftover conversions to kfree_rcu().  Almost
all of the latter need either an Acked-by or to be taken into the
appropriate maintainer tree.  The patches are as follows:

1.	Simplify RCU kthread creation.
2.	Convert from kthread_create() to kthread_create_on_node()
	(courtesy of Eric Dumazet).
3.	Improve rcu_read_lock() code generation.
4.	Restore checks for blocking within RCU read-side critical
	sections under CONFIG_PROVE_RCU.
5.	Move struct rcu_head into types.h as a first step towards
	untangling header files.
6.	Update rcutorture documentation to account for boosting,
	memory-barrier testing, and (not so) new flavors of RCU.
7.	Fix type mismatch (courtesy of Andi Kleen).
8.	Combine common grace-period-wait code.
9.	Eliminate rcutorture workarounds for previously missing
	RCU API members, and add testing of synchronize_rcu_bh_expedited().
10.	Update RCU's NMI documentation.
11-27.	Conversions to kfree_rcu() (courtesy of Lai Jiangshan,
	in need of either Acked-by or adoption).
28.	Convert call_rcu(sk_filter_release_rcu) to kfree_rcu
	(courtesy of Lai Jiangshan, already acked).

For a testing-only version of this patchset from git, please see the
