The LPI pending status for a GICv3 redistributor is held in a table in (guest) memory. To achieve reasonable performance, we cache the pending bit in our struct vgic_irq. The initial pending state must be read from guest memory upon enabling LPIs for this redistributor. As we can't access the guest memory while we hold the lpi_list spinlock, we create a snapshot of the LPI list and iterate over that.
