Subject: [PATCH v2 1/5] KVM: SVM: Drop unneeded CONFIG_X86_LOCAL_APIC check for AVIC
Date: Tue, 18 May 2021 16:43:35 +0200	[thread overview]
Message-ID: <20210518144339.1987982-2-vkuznets@redhat.com> (raw)
In-Reply-To: <20210518144339.1987982-1-vkuznets@redhat.com>

AVIC dependency on CONFIG_X86_LOCAL_APIC is dead code since
commit e42eef4ba388 ("KVM: add X86_LOCAL_APIC dependency").
