e1444b5a16 IB/cm: Fix automatic path migration support
The ib_cm_establish() function is replaced with a more generic
ib_cm_notify().  This routine is used to notify the CM that failover
has occurred, so that future CM messages (LAP, DREQ) reach the remote
CM.  (Currently, we continue to use the original path)  This bumps the
userspace CM ABI.

New alternate path information is captured when a LAP message is sent
or received.  This allows QP attributes to be initialized for the user
when a new path is loaded after failover occurs.

75af908851 IB/ucm: Get rid of duplicate P_Key parameter
The P_Key is provided into a SIDR REQ in two places, once as a
parameter, and again in the path record.  Remove the P_Key as a
parameter and always use the one given in the path record.

This change has no practical effect on ABI functionality.

6e61d04f2d IB/cm: Match connection requests based on private data
Extend matching connection requests to listens in the InfiniBand CM to
include private data checks.

This allows applications to listen on the same service identifier,
with private data directing the request to the appropriate application.

a4d61e8480 [PATCH] IB: move include files to include/rdma
Move the InfiniBand headers from drivers/infiniband/include to include/rdma.
This allows InfiniBand-using code to live elsewhere, and lets us remove the
ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles.
