Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull rdma fixes from Doug Ledford:
 "This has been a slow -rc cycle for the RDMA subsystem. We really
  haven't had a lot of rc fixes come in. This pull request is the first
  of this entire rc cycle and it has all of the suitable fixes so far
  and it's still only about 20 patches. The fix for the minor breakage
  cause by the dma mapping patchset is in here, as well as a couple
  other potential oops fixes, but the rest is more minor.

  Summary:

   - fix for dma_ops change in this kernel, resolving the s390, powerpc,
     and IOMMU operation

   - a few other oops fixes

   - the rest are all minor fixes"
