Subject: [PATCH v3 26/31] KVM: MMU: set ad_disabled in TDP MMU role
Date: Fri, 24 Sep 2021 12:31:47 -0400 [thread overview]
Message-ID: <20210924163152.289027-27-pbonzini@redhat.com> (raw)
In-Reply-To: <20210924163152.289027-1-pbonzini@redhat.com>
Prepare for removing the ad_disabled argument of make_spte; instead it can
be found in the role of a struct kvm_mmu_page. First of all, the TDP MMU
must set the role accurately.
