Subject: [PATCH tip/core/rcu 0/3] signed overflow, virtualization
 optimizations, deadlock avoidance

Hello!

This patchset adds a few more commits to the list:

1.	Rework check_cpu_stall to avoid signed overflow.
2.	Provide an RCU API for better detection of running in a
	guest OS (thanks to Gleb Natapov).
3.	Permit rcu_read_unlock() to be called while holding one
	of the runqueue locks in response to a lockdep splat,
	quite possibly from Valdis Kletnieks.

For a testing-only version of this patchset from git, please see the
following subject-to-rebase branch:

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/testing

							Thanx, Paul
