Subject: [PATCH V3]  kvm:x86 :remove unnecessary recalculate_apic_map
Date:   Tue, 4 Dec 2018 17:42:50 +0800
Message-Id: <1543916570-55054-1-git-send-email-peng.hao2@zte.com.cn>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In the previous code, the variable apic_sw_disabled influences
recalculate_apic_map. But in "KVM: x86: simplify kvm_apic_map"
(commit:3b5a5ffa928a3f875b0d5dd284eeb7c322e1688a),
the access to apic_sw_disabled in recalculate_apic_map has been
deleted.
