Sorry for the confusion.

The patch at
http://lkml.org/lkml/2010/10/13/67 resolves the issue.

But this is not a part of 2.6.36-git6 , when will it be pulled into the upstream?

Thanks
Divya

That patch is splited into two parts.
The lockdep one is 4ba053c04aece1f4734056f21b751eee47ea3fb1 upstream.
The mousedev one is taken by Dmitry Torokhov(Cc'ing)

Just notice Dmitry has sent pull request to Linus.
You can also get the mousedev one here:
