kvm->irq_lock protects too much stuff, but still fail to protect everything it was design to protect (see ack notifiers call in pic). I want to make IRQ injection fast path as lockless as possible. This patch series removes kvm->irq_lock from irq injection path effectively making interrupt injection to lapic lockless (several kvm_irq_delivery_to_apic() may run in parallel), but access to lapic was never fully locked in the first place. VCPU could access lapic in parallel with interrupt injection. Patches 2-3 changes irq routing data structure to much more efficient one.
