Subject: [GIT PULL] rcu: finalize debugobjects, first round of RCU sparse
 pointer checks

Hello, Ingo,

Here are the final commits from Mathieu's debugobjects series and the
first few from Arnd's RCU-pointer sparse series.  The first three remove
RCU's (useless) initializations from mm, fs, and powerpc:

mm:	http://lkml.org/lkml/2010/5/18/562
fs:	http://lkml.org/lkml/2010/5/18/500
powerpc:http://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg43510.html

Kosaki Motohiro agreed that the mm patch should go up -tip, and none of
the other maintainers objected to the prospect of their patches going
up -tip.

The fourth patch removes RCU's initialization definitions, and the final
four patches provide the beginnings of Arnd's RCU-pointer sparse checks.

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

Or, if you prefer this against 2.6.34-rc7 without a merge record:

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/next-rc7

If you would rather me rebase this stack against 2.6.35-rc1, let me know!

Either way, once these commits reach mainline, I will submit the next 21
commits to their respective trees.  The maintainers have been CCed on the
earlier LKML patchsets (http://lkml.org/lkml/2010/5/12/372).  Once these
21 commits hit mainline, I will send you a pull request for the remaining
two commits.

Then on to CONFIG_TINY_PREEMPT_RCU.

							Thanx, Paul
