[PATCH v2 16/16] KVM: PPC: Book3S HV: XIVE: clear the vCPU interrupt presenters

2019-02-22 Thread Cédric Le Goater
When the VM boots, the CAS negotiation process determines which interrupt mode to use and invokes a machine reset. At that time, the previous KVM interrupt device is 'destroyed' before the chosen one is created. Upon destruction, the vCPU interrupt presenters using the KVM device should be cleared
