[GIT PULL] VFIO fixes for v4.10-rc3

[Alex Williamson]

Hi Linus,

This pull request has a merge conflict and requires a build fix with
kvmgt (merged in ed40875), which is a consumer of the new vfio-mdev
work.  Stephen Rothwell has fixed both of these correctly for
linux-next as documented here:

Please make the corresponding changes in your merge.  Thanks!

Alex
