Avi Kivity 8c35f237fb KVM: Route irq 0 to vcpu 0 exclusively 
Some Linux versions allow the timer interrupt to be processed by more than
one cpu, leading to hangs due to tsc instability.  Work around the issue
by only disaptching the interrupt to vcpu 0.

Problem analyzed (and patch tested) by Sheng Yang.
