[GIT PULL] NTB bug fixes for v4.13

[Jon Mason]

Hello Linus,
Here are a number of NTB changes for 4.13.

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.

This series has been tested very heavily on the previous version of the
kernel, and is compartmentalized to the ntb code.  So even if something
was broken, there should be no ill effects to other subsystems.

Please consider pulling it.

Thanks,
Jon
