Subject: [PATCH 5/5] KVM: x86: Use lapic_in_kernel() to query in-kernel APIC in APICv helper
Date: Tue, 14 Jun 2022 23:05:48 +0000 [thread overview]
Message-ID: <20220614230548.3852141-6-seanjc@google.com> (raw)
In-Reply-To: <20220614230548.3852141-1-seanjc@google.com>
Use lapic_in_kernel() in kvm_vcpu_apicv_active() to take advantage of the
kvm_has_noapic_vcpu static branch.
No functional change intended.
