Now applied, thanks.

Also, can you look into the merge of 3.14-rc2 into the driver-core-next
branch?  There are some conflicts in the kernfs code due to the lockdep
changes that I couldn't easily verify I got right, so I didn't do the
merge.  Could you give me a diff of the merge for me to work off of?

thanks,
