Here's the big char/misc driver update for 3.20-rc1. Lots of little things in here, all described in the changelog. Nothing major or unusual, except maybe the binder selinux stuff, which was all acked by the proper selinux people and they thought it best to come through this tree. All of this has been in linux-next with no reported issues for a while.
