From 187ca84b4b02d8b8a4f2117f1c6b209ef1ee90fc Mon Sep 17 00:00:00 2001 From: Wanpeng Li Date: Wed, 3 Aug 2016 12:04:13 +0800 Subject: [PATCH] KVM: lapic: don't recalculate apic map table twice when enabling LAPIC MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit APIC map table is recalculated during reset APIC ID to the initial value when enabling LAPIC. This patch move the recalculate_apic_map() to the next branch since we don't need to recalculate apic map twice in current codes.
