Merge tag 'vfio-v6.16-rc1' of https://github.com/awilliam/linux-vfio

Pull VFIO updates from Alex Williamson:

 - Remove an outdated DMA unmap optimization that relies on a feature
   only implemented in AMDv1 page tables. (Jason Gunthorpe)

 - Fix various migration issues in the hisi_acc_vfio_pci variant driver,
   including use of a wrong DMA address requiring an update to the
   migration data structure, resending task completion interrupt after
   migration to re-sync queues, fixing a write-back cache sequencing
   issue, fixing a driver unload issue, behaving correctly when the
   guest driver is not loaded, and avoiding to squash errors from
   sub-functions. (Longfang Liu)

 - mlx5-vfio-pci variant driver update to make use of the new two-step
   DMA API for migration, using a page array directly rather than using
   a page list mapped across a scatter list. (Leon Romanovsky)

 - Fix an incorrect loop index used when unwinding allocation of dirty
   page bitmaps on error, resulting in temporary failure in freeing
   unused bitmaps. (Li RongQing)
