Merge tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband
Pull infiniband updates from Roland Dreier:
"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"
