    KVM: PPC: Book3S HV: Counters for passthrough IRQ stats · 65e7026a
    Suresh Warrier authored
    Add VCPU stat counters to track affinity for passthrough
    interrupts.
    
    pthru_all: Counts all passthrough interrupts whose IRQ mappings are
               in the kvmppc_passthru_irq_map structure.
    pthru_host: Counts all cached passthrough interrupts that were injected
    	    from the host through kvm_set_irq (i.e. not handled in
    	    real mode).
    pthru_bad_aff: Counts how many cached passthrough interrupts have
                   bad affinity (receiving CPU is not running VCPU that is
    	       the target of the virtual interrupt in the guest).
