Pull rdma fixes from Doug Ledford:
 "No beating around the bush: this is a monster pull request for an -rc5
  kernel. Intel hit me with a series of fixes for TID processing.
  Mellanox hit me with a series for their UMR memory support.

  And we had one fix for siw that fixes the 32bit build warnings and
  because of the number of casts that had to be changed to properly
  silence the warnings, that one patch alone is a full 40% of the LOC of
  this entire pull request. Given that this is the initial release
  kernel for siw, I'm trying to fix anything in it that we can, so that
  adds to the impetus to take fixes for it like this one.

  I had to do a rebase early in the week. Jason had thought he put a
  patch on the rc queue that he needed to be there so he could base some
  work off of it, and it had actually not been placed there. So he asked
  me (on Tuesday) to fix that up before pushing my wip branch to the
  official rc branch. I did, and that's why the early patches look like
  they were all committed at the same time on Tuesday. That bunch had
  been in my queue prior.

  The various patches all pass my test for being legitimate fixes and
  not attempts to slide new features or development into a late rc.
  Well, they were all fixes with the exception of a couple clean up
  patches people wrote for making the fixes they also wrote better (like
  a cleanup patch to move UMR checking into a function so that the
  remaining UMR fix patches can reference that function), so I left
  those in place too.

  My apologies for the LOC count and the number of patches here, it's
  just how the cards fell this cycle.

  Summary:

   - Fix siw buffer mapping issue

   - Fix siw 32/64 casting issues

   - Fix a KASAN access issue in bnxt_re

   - Fix several memory leaks (hfi1, mlx4)

   - Fix a NULL deref in cma_cleanup

   - Fixes for UMR memory support in mlx5 (4 patch series)

   - Fix namespace check for restrack

   - Fixes for counter support

   - Fixes for hfi1 TID processing (5 patch series)

   - Fix potential NULL deref in siw

   - Fix memory page calculations in mlx5"
