Linus Torvalds cebcffe666 VFIO updates for v7.0-rc1
- Update outdated mdev comment referencing the renamed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)
