From 44944d4d28948c71b110b09a2e924e505cd39e8b Mon Sep 17 00:00:00 2001 From: Yang Zhang Date: Sun, 7 Apr 2013 08:25:18 +0800 Subject: KVM: Call kvm_apic_match_dest() to check destination vcpu For a given vcpu, kvm_apic_match_dest() will tell you whether the vcpu in the destination list quickly. Drop kvm_calculate_eoi_exitmap() and use kvm_apic_match_dest() instead.
