Can't you just register a delayed funtion in
kfd_process_notifier_release() and call amd_iommu_unbind_pasid() from
there? I really hate to make that part of the IOMMUv2 driver API,
especially since it is going to be turned into a generic IOMMU-API
extension.

And especially since all these hacks could be avoided if the KFD driver
would just turn down everything on closing the file descriptor.
