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

Pull rdma fixes from Doug Ledford:
 "This is our first pull request of the rc cycle. It's not that it's
  been overly quiet, we were just waiting on a few things before sending
  this off.

  For instance, the 6 patch series from Intel for the hfi1 driver had
  actually been pulled in on Tuesday for a Wednesday pull request, only
  to have Jason notice something I missed, so we held off for some
  testing, and then on Thursday had to respin the series because the
  very first patch needed a minor fix (unnecessary cast is all).

  There is a sizable hns patch series in here, as well as a reasonably
  largish hfi1 patch series, then all of the lines of uapi updates are
  just the change to the new official Linux-OpenIB SPDX tag (a bunch of
  our files had what amounts to a BSD-2-Clause + MIT Warranty statement
  as their license as a result of the initial code submission years ago,
  and the SPDX folks decided it was unique enough to warrant a unique
  tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4
  and core/cache/cma updates to round out the bunch.

  None of it was overly large by itself, but in the 2 1/2 weeks we've
  been collecting patches, it has added up :-/.

  As best I can tell, it's been through 0day (I got a notice about my
  last for-next push, but not for my for-rc push, but Jason seems to
  think that failure messages are prioritized and success messages not
  so much). It's also been through linux-next. And yes, we did notice in
  the context portion of the CMA query gid fix patch that there is a
  dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage
  and remove it anywhere we can.

  Summary:

   - Various build fixes (USER_ACCESS=m and ADDR_TRANS turned off)

   - SPDX license tag cleanups (new tag Linux-OpenIB)

   - RoCE GID fixes related to default GIDs

   - Various fixes to: cxgb4, uverbs, cma, iwpm, rxe, hns (big batch),
     mlx4, mlx5, and hfi1 (medium batch)"
