[PATCH] KVM: nVMX: Morph notification vector IRQ on nested VM-Enter to pending PI

2020-08-12 Thread Sean Christopherson
On successful nested VM-Enter, check for pending interrupts and convert the highest priority interrupt to a pending posted interrupt if it matches L2's notification vector. If the vCPU receives a notification interrupt before nested VM-Enter (assuming L1 disables IRQs before doing VM-Enter), the p
