    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
