Subject: [GIT PULL rcu/urgent] Banishing kthreads

Hello, Ingo,

This pull request banishes RCU kthreads in the RCU_BOOST=n case,
in response to popular demand.  There are two commits in this
series:

1.	Minimal patch that #ifdefs out the kthread code.

2.	Code-movement patch that puts the code #ifdefed out above
	under existing #ifdefs in kernel/rcutree_plugin.h.

These changes are available in the git repository at:

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

  							Thanx, Paul
