Subject: [PATCH v3 4/7] KVM: nVMX: Rename nested_ept_get_cr3() to nested_ept_get_eptp()
Date: Mon, 2 Mar 2020 18:02:37 -0800 [thread overview]
Message-ID: <20200303020240.28494-5-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200303020240.28494-1-sean.j.christopherson@intel.com>
Rename the accessor for vmcs12.EPTP to use "eptp" instead of "cr3". The
accessor has no relation to cr3 whatsoever, other than it being assigned
to the also poorly named kvm_mmu->get_cr3() hook.
No functional change intended.
