Hi Linus,

Please pull from

    git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git tags/rdma-for-linus

----------------------------------------------------------------

Main batch of InfiniBand/RDMA changes for 3.15:

 - The biggest change is core API extensions and mlx5 low-level driver
   support for handling DIF/DIX-style protection information, and the
   addition of PI support to the iSER initiator.  Target support will be
   arriving shortly through the SCSI target tree.

 - A nice simplification to the "umem" memory pinning library now that
   we have chained sg lists.  Kudos to Yishai Hadas for realizing our
   code didn't have to be so crazy.

 - Another nice simplification to the sg wrappers used by qib, ipath and
   ehca to handle their mapping of memory to adapter.

 - The usual batch of fixes to bugs found by static checkers etc. from
   intrepid people like Dan Carpenter and Yann Droneaud.

 - A large batch of cxgb4, ocrdma, qib driver updates.
