#     Merge tag 'vfio-v6.2-rc6' of https://github.com/awilliam/linux-vfio
#     
#     Pull VFIO fixes from Alex Williamson:
#     
#      - Honor reserved regions when testing for IOMMU find grained super page
#        support, avoiding a regression on s390 for a firmware device where
#        the existence of the mapping, even if unused can trigger an error
#        state. (Niklas Schnelle)
#     
#      - Fix a deadlock in releasing KVM references by using the alternate
#        .release() rather than .destroy() callback for the kvm-vfio device.
#        (Yi Liu)
