arm/arm64: KVM: vgic: Clear queued flags on unqueue
If we unqueue a level-triggered interrupt completely, and the LR does not stick around in the active state (and will therefore no longer generate a maintenance interrupt), then we should clear the queued flag so that the vgic can actually queue this level-triggered interrupt at a later time and deal with its pending state then. Note: This should actually be properly fixed to handle the active state on the distributor. Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
