Merge tag 'vfio-v6.17-rc1-v2' of https://github.com/awilliam/linux-vfio

Pull VFIO updates from Alex Williamson:

 - Fix imbalance where the no-iommu/cdev device path skips too much on
   open, failing to increment a reference, but still decrements the
   reference on close. Add bounds checking to prevent such underflows
   (Jacob Pan)

 - Fill missing detach_ioas op for pds_vfio_pci, fixing probe failure
   when used with IOMMUFD (Brett Creeley)

 - Split SR-IOV VFs to separate dev_set, avoiding unnecessary
   serialization between VFs that appear on the same bus (Alex
   Williamson)

 - Fix a theoretical integer overflow is the mlx5-vfio-pci variant
   driver (Artem Sadovnikov)

 - Implement missing VF token checking support via vfio cdev/IOMMUFD
   interface (Jason Gunthorpe)

 - Update QAT vfio-pci variant driver to claim latest VF devices
   (Małgorzata Mielnik)

 - Add a cond_resched() call to avoid holding the CPU too long during
   DMA mapping operations (Keith Busch)
