Subject: [PATCH 03/10] KVM: x86: rename apic_access_page_done to apic_access_memslot_enabled
Date: Wed, 23 Jun 2021 14:29:55 +0300 [thread overview]
Message-ID: <20210623113002.111448-4-mlevitsk@redhat.com> (raw)
In-Reply-To: <20210623113002.111448-1-mlevitsk@redhat.com>
This better reflects the purpose of this variable on AMD, since
on AMD the AVIC's memory slot can be enabled and disabled dynamically.
