Subject: kvm: x86: remove unnecessary recalculate_apic_map
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eb1ff0a913ca092ae5a4e7c9277b0a634c645eee;p=openwrt%2Fstaging%2Fblogic.git

kvm: x86: remove unnecessary recalculate_apic_map

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.
