Merge branch 'for-next-early' into for-next

The early for-next branch was based on v4.14-rc2, while the shared pull
request I got from Mellanox used a v4.14-rc4 base.  I'm making the
branch that was the shared Mellanox pull request the new for-next branch
and merging the early for-next branch into it.
