Pull NTB updates from Jon Mason:
 "The major change in the series is a rework of the NTB infrastructure
  to all for IDT hardware to be supported (and resulting fallout from
  that). There are also a few clean-ups, etc.

  New IDT NTB driver and changes to the NTB infrastructure to allow for
  this different kind of NTB HW, some style fixes (per Greg KH
  recommendation), and some ntb_test tweaks"
