  vfio/pci: Reject invalid MSI-X Table and PBA BIR values (2026-07-07 07:12:46 +0200)

----------------------------------------------------------------
vfio queue:

* Fixes ROM read issues in vfio/pci: information leak, error
  propagation, and uninitialized state
* Validates VERSION replies in vfio-user and updates the spec
  for DMA access mode bits
* Merges .dma_map_file() into .dma_map() in the iommufd backend
* Reworks switchover-ack to be re-usable and implements the
  VFIO_PRECOPY_INFO_REINIT feature for additional pre-copy
  iterations before switchover
* Adds ATS support for passthrough devices via iommufd
* Fixes translated_addr for non-identity-mapped RAM sections in
  the VFIO listener
* Reject invalid MSI-X Table and PBA BIR values
