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:


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:// rcu/next

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

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 ( Once these
21 commits hit mainline, I will send you a pull request for the remaining
two commits.


Thanx, Paul
