external () not needed here. bit 5 might be clearer as bit / 32
We're currently using a counter to track the most recent GSI we've
handed out. This quickly hits KVM_MAX_IRQ_ROUTES when using device
assignment with a driver that regularly toggles the MSI enable bit.
This can mean only a few minutes of usable run time. Instead, track
used GSIs in a bitmap.
