    Pull inifiniband/rdma updates from Doug Ledford:
     "This is a fairly sizeable set of changes.  I've put them through a
      decent amount of testing prior to sending the pull request due to
      that.
    
      There are still a few fixups that I know are coming, but I wanted to
      go ahead and get the big, sizable chunk into your hands sooner rather
      than waiting for those last few fixups.
    
      Of note is the fact that this creates what is intended to be a
      temporary area in the drivers/staging tree specifically for some
      cleanups and additions that are coming for the RDMA stack.  We
      deprecated two drivers (ipath and amso1100) and are waiting to hear
      back if we can deprecate another one (ehca).  We also put Intel's new
      hfi1 driver into this area because it needs to be refactored and a
      transfer library created out of the factored out code, and then it and
      the qib driver and the soft-roce driver should all be modified to use
      that library.
    
      I expect drivers/staging/rdma to be around for three or four kernel
      releases and then to go away as all of the work is completed and final
      deletions of deprecated drivers are done.
    
      Summary of changes for 4.3:
    
       - Create drivers/staging/rdma
       - Move amso1100 driver to staging/rdma and schedule for deletion
       - Move ipath driver to staging/rdma and schedule for deletion
       - Add hfi1 driver to staging/rdma and set TODO for move to regular
         tree
       - Initial support for namespaces to be used on RDMA devices
       - Add RoCE GID table handling to the RDMA core caching code
       - Infrastructure to support handling of devices with differing read
         and write scatter gather capabilities
       - Various iSER updates
       - Kill off unsafe usage of global mr registrations
       - Update SRP driver
       - Misc  mlx4 driver updates
       - Support for the mr_alloc verb
       - Support for a netlink interface between kernel and user space cache
         daemon to speed path record queries and route resolution
       - Ininitial support for safe hot removal of verbs devices"
