Subject: [PATCH rcu/urgent] Banishing kthreads

This patchset banishes RCU kthreads from non-RCU_BOOST kernel threads.
The two patches are as follows:

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.

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/urgent

								Thanx, Paul
