Heyi Guo d4a8061a7c KVM: arm/arm64: vgic: Fix potential deadlock when ap_list is long ... If the ap_list is longer than 256 entries, merge_final() in list_sort() will call the comparison callback with the same element twice, causing a deadlock in vgic_irq_cmp(). Fix it by returning early when irqa == irqb.
