    Merge tag 'ntb-4.15' of git://github.com/jonmason/ntb
    
    Pull ntb updates from Jon Mason:
     "Support for the switchtec ntb and related changes. Also, a couple of
      bug fixes"
    
    [ The timing isn't great. I had asked people to send me pull requests
      before my family vacation, and this code has not even been in
      linux-next as far as I can tell. But Logan Gunthorpe pleaded for its
      inclusion because the Switchtec driver has apparently been around for
      a while, just never in linux-next - Linus ]
