Subject: [PATCH 0/2] KVM: arm64: vgic_irq: Fix memory leaks

A memory leak on vgic_irq structure was recently reported by kmemleak
on the guest destroy (or shutdown). It turned out that there're still
pending interrupts (LPI) staying in the vcpu's ap_list during destroy
so that KVM can't free the vgic_irq structure due to an extra refcount.

Patch #1 is intended to fix this issue. Patch #2 is a memory leak fix
on the error path, noticed while debugging.

Zenghui Yu (2):
  KVM: arm64: vgic-v3: Retire all pending LPIs on vcpu destroy
  KVM: arm64: vgic-its: Fix memory leak on the error path of
    vgic_add_lpi()
