I've already fixed some/all of this in my iommu/pci branch:
https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/commit/?h=iommu/pci&id=d4e46030b91367b50ecb544fee021b30e4ec4e9a
Can you try rebasing on that and see if there's anything left to do, please?
Once we get to -rc1, I'll sort out my branches so the iommu/devel branch
will contain stuff that I consider candidates for merging (since the
iommu/pci branch contains a bunch of WIP/RFC stuff too)
Cheers,
Will
