Merge tag 'for-linus' of git://github.com/dledford/linux 

Pull infiniband updates from Doug Ledford:
 "Minor updates for 4.1-rc

  Most of the changes are fairly small and well confined.  The iWARP
  address reporting changes are the only ones that are a medium size.  I
  had these queued up prior to rc1, but due to the shuffle in
  maintainers, they did not get submitted when I expected.  My apologies
  for that.  I feel comfortable with them however due to the testing
  they've received, so I left them in this submission"
