FYI, I first tried this vfio-8.2 branch on s390x but wasn't actually able to
use the
iommufd backend (was getting errors like Property 'vfio-pci.iommufd' not found)
so I think something isn't actually enabling IOMMUFD as expected with your
change...
It looks CONFIG_IOMMUFD is recognized by Kconfig sub-system but not received
by compiler. I'm still digging how to pass CONFIG_IOMMUFD to compiler.
Need below change to pass CONFIG_IOMMUFD to compiler.

yep. I pushed forced vfio-8.2 with these changes.
Thanks,
