Sean Christopherson bbc13ae593 VFIO: KVM: x86: Drop kvm_arch_{start,end}_assignment() ... Drop kvm_arch_{start,end}_assignment() and all associated code now that KVM x86 no longer consumes assigned_device_count. Tracking whether or not a VFIO-assigned device is formally associated with a VM is fundamentally flawed, as such an association is optional for general usage, i.e. is prone to false negatives. E.g. prior to commit 2edd9cb79f ("kvm: detect assigned device via irqbypass manager"), device passthrough via VFIO would fail to enable IRQ bypass if userspace omitted the formal VFIO<=>KVM binding. And device drivers that *need* the VFIO<=>KVM connection, e.g. KVM-GT, shouldn't be relying on generic x86 tracking infrastructure.
