Linus Torvalds f0bf3eac92 VFIO updates for v7.1-rc1
- Update QAT vfio-pci variant driver for Gen 5, 420xx devices.
    (Vijay Sundar Selvamani, Suman Kumar Chakraborty, Giovanni Cabiddu)
 
  - Fix vfio selftest MMIO DMA mapping selftest. (Alex Mastro)
 
  - Conversions to const struct class in support of class_create()
    deprecation. (Jori Koolstra)
 
  - Improve selftest compiler compatibility by avoiding initializer
    on variable-length array. (Manish Honap)
 
  - Define new uAPI for drivers supporting migration to advise user-
    space of new initial data for reducing target startup latency.
    Implemented for mlx5 vfio-pci variant driver. (Yishai Hadas)
 
  - Enable vfio selftests on aarch64, not just cross-compiles reporting
    arm64. (Ted Logan)
 
  - Update vfio selftest driver support to include additional DSA
    devices. (Yi Lai)
 
  - Unconditionally include debugfs root pointer in vfio device struct,
    avoiding a build failure seen in hisi_acc variant driver without
    debugfs otherwise. (Arnd Bergmann)
 
  - Add support for the s390 ISM (Internal Shared Memory) device via
    a new variant driver.  The device is unique in the size of its BAR
    space (256TiB) and lack of mmap support. (Julian Ruess)
 
  - Enforce that vfio-pci drivers implement a name in their ops
    structure for use in sequestering SR-IOV VFs. (Alex Williamson)
 
  - Prune leftover group notifier code. (Paolo Bonzini)
 
  - Fix Xe vfio-pci variant driver to avoid migration support as a
    dependency in the reset path and missing release call.
