linux-next: strange commit in the uprobes tree

Hi Srikar,

I just fetched the uprobes tree and noticed that commit 05f7cebbdbc8
("rcu: Introduce bulk reference count") has no patch, just a commit
message.   In the previous version of your tree, the commit had Paul as
author and now has you (which is what brought it to my attention), but
the lack of patch is more interesting ... I do notice that there is
another patch from Paul ("rcu: Introduce raw SRCU read-side primitives")
and was wondering if that replaces the above patch.

Thanks Stephen for reporting this.  yes, the patch from Paul replaces
the empty commit that you see.  After I cherry-picked the 3 commits from
the -tip tree, I had pushed my existing patches that had older Paul's
bulkref patch (removed the changes as part of merge; thats why it shows
my name in author for the faulty commit;) I should have removed the
commit. 

Sorry for the inconvienience.
