[GIT PULL] VFIO updates for v6.17-rc1 v2

[Alex Williamson]

Hi Linus,

I've dropped the series with the troublesome mm helper in this pull
request.  We'll continue to work towards something acceptable there and
re-target it for v6.18.  Thanks,

Alex

  vfio/type1: conditional rescheduling while pinning (2025-08-05 15:41:19 -0600)

----------------------------------------------------------------
VFIO updates for v6.17-rc1 v2

 - 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)
