Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rmda fixes from Doug Ledford.
"First round of -rc fixes.
Due to various issues, I've been away and couldn't send a pull request
for about three weeks. There were a number of -rc patches that built
up in the meantime (some where there already from the early -rc
stages). Obviously, there were way too many to send now, so I tried to
pare the list down to the more important patches for the -rc cycle.
Most of the code has had plenty of soak time at the various vendor's
testing setups, so I doubt there will be another -rc pull request this
cycle. I also tried to limit the patches to those with smaller
footprints, so even though a shortlog is longer than I would like, the
actual diffstat is mostly very small with the exception of just three
files that had more changes, and a couple files with pure removals.
Summary:
- Misc Intel hfi1 fixes
- Misc Mellanox mlx4, mlx5, and rxe fixes
- A couple cxgb4 fixes"
