Merge tag 'kvm-x86-no_assignment-6.17' of https://github.com/kvm-x86/linux into HEAD
KVM VFIO device assignment cleanups for 6.17
Kill off kvm_arch_{start,end}_assignment() and x86's associated tracking now
that KVM no longer uses assigned_device_count as a bad heuristic for "VM has
an irqbypass producer" or for "VM has access to host MMIO".
