Linus Torvalds 244aefb1c6 VFIO updates for v6.8-rc1

- Add debugfs support, initially used for reporting device migration
    state. (Longfang Liu)
 
  - Fixes and support for migration dirty tracking across multiple IOVA
    regions in the pds-vfio-pci driver. (Brett Creeley)
 
  - Improved IOMMU allocation accounting visibility. (Pasha Tatashin)
 
  - Virtio infrastructure and a new virtio-vfio-pci variant driver, which
    provides emulation of a legacy virtio interfaces on modern virtio
    hardware for virtio-net VF devices where the PF driver exposes
    support for legacy admin queues, ie. an emulated IO BAR on an SR-IOV
    VF to provide driver ABI compatibility to legacy devices.
    (Yishai Hadas & Feng Liu)
 
  - Migration fixes for the hisi-acc-vfio-pci variant driver.
    (Shameer Kolothum)
 
  - Kconfig dependency fix for new virtio-vfio-pci variant driver.
    (Arnd Bergmann)
