[GIT PULL] VFIO updates for v7.0-rc1

[Alex Williamson <alex@shazbot.org>]

Hi Linus,

There are a couple unusual block file changes here that come via a
shared branch from Jens[1].  Otherwise 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.
Thanks,

Alex

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 - Update outdated mdev comment referencing the renamed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)
