    KVM: x86: do not scan IRR twice on APICv vmentry · 76dfafd5
    Paolo Bonzini authored
    Calls to apic_find_highest_irr are scanning IRR twice, once
    in vmx_sync_pir_from_irr and once in apic_search_irr.  Change
    sync_pir_from_irr to get the new maximum IRR from kvm_apic_update_irr;
    now that it does the computation, it can also do the RVI write.
    
    In order to avoid complications in svm.c, make the callback optional.
