Merge tag 'vfio-v7.0-rc1' of https://github.com/awilliam/linux-vfio

Pull VFIO updates from Alex Williamson:
 "A small cycle with the bulk in selftests and reintroducing poison
  handling in the nvgrace-gpu driver. The rest are fixes, cleanups, and
  some dmabuf structure consolidation.

   - Update outdated mdev comment referencing the renamed
     mdev_type_add() function (Julia Lawall)

   - Introduce selftest support for IOMMU mapping of PCI MMIO BARs (Alex
     Mastro)

   - Relax selftest assertion relative to differences in huge page
     handling between legacy (v1) TYPE1 IOMMU mapping behavior and the
     compatibility mode supported by IOMMUFD (David Matlack)

   - Reintroduce memory poison handling support for non-struct-page-
     backed memory in the nvgrace-gpu variant driver (Ankit Agrawal)

   - Replace dma_buf_phys_vec with phys_vec to avoid duplicate structure
     and semantics (Leon Romanovsky)

   - Add missing upstream bridge locking across PCI function reset,
     resolving an assertion failure when secondary bus reset is used to
     provide that reset (Anthony Pighin)

   - Fixes to hisi_acc vfio-pci variant driver to resolve corner case
     issues related to resets, repeated migration, and error injection
     scenarios (Longfang Liu, Weili Qian)

   - Restrict vfio selftest builds to arm64 and x86_64, resolving
     compiler warnings on 32-bit archs (Ted Logan)

   - Un-deprecate the fsl-mc vfio bus driver as a new maintainer has
     stepped up (Ioana Ciornei)"

* tag 'vfio-v7.0-rc1' of https://github.com/awilliam/linux-vfio:
  vfio/fsl-mc: add myself as maintainer
  vfio: selftests: only build tests on arm64 and x86_64

  vfio/pci: Lock upstream bridge for vfio_pci_core_disable()
  types: reuse common phys_vec type instead of DMABUF open‑coded variant
  vfio/nvgrace-gpu: register device memory for poison handling
  mm: add stubs for PFNMAP memory failure registration functions
  vfio: selftests: Drop IOMMU mapping size assertions for VFIO_TYPE1_IOMMU
  vfio: selftests: Add vfio_dma_mapping_mmio_test
  vfio: selftests: Align BAR mmaps for efficient IOMMU mapping
