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 3.19:

 - On-demand paging support in core midlayer and mlx5 driver.  This lets
   userspace create non-pinned memory regions and have the adapter HW
   trigger page faults.
 - iSER and IPoIB updates and fixes.
 - Low-level HW driver updates for cxgb4, mlx4 and ocrdma.
 - Other miscellaneous fixes.
