9a7147b506 RDMA: Update exported headers list
Various RDMA headers are intended to be exported to userspace, so add
them to the headers-y list.  Add a (strictly speaking, superfluous)
include of <linux/types.h> to avoid a headers_check warning.

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.

7b28b0d000 [IB] ucm: 32/64 compatibility fixes
Fix structure layouts to ensure same size on 32-bit and 64-bit architectures.
This permits 32-bit userspace apps on a 64-bit kernel.

0b2b35f681 [PATCH] IB: Add user-supplied context to userspace CM ABI
- Add user specified context to all uCM events.  Users will not retrieve
  any events associated with the context after destroying the corresponding
  cm_id.
- Provide the ib_cm_init_qp_attr() call to userspace clients of the CM.
  This call may be used to set QP attributes properly before modifying the QP.
- Fixes some error handling synchonization and cleanup issues.
- Performs some minor code cleanup.

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.
