Jason Gunthorpe (4):
IB/cm: Pair cm_alloc_response_msg() with a cm_free_response_msg()
IB/cm: Split cm_alloc_msg()
IB/cm: Call the correct message free functions in cm_send_handler()
IB/cm: Tidy remaining cm_msg free paths

Mark Zhang (4):
Revert "IB/cm: Mark stale CM id's whenever the mad agent was
unregistered"
IB/cm: Simplify ib_cancel_mad() and ib_modify_mad() calls
IB/cm: Improve the calling of cm_init_av_for_lap and
cm_init_av_by_path
IB/cm: Protect cm_dev, cm_ports and mad_agent with kref and lock
