Hi Stephen, sorry about those merges today.  The proper fix is queued
up in patchwork for when net-next is merged in to net:

http://patchwork.ozlabs.org/patch/851063/

I will CC you on patches which may cause/fix merge trouble in the
future, often the information about how to resolve the conflict is
not part of the commit message.

Sorry I didn't think about CCing you earlier!
