From 871bd0346018df53055141f09754cb5ffb334c7b Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 1 Aug 2019 13:35:21 -0700 Subject: KVM: x86: Rename access permissions cache member in struct kvm_vcpu_arch Rename "access" to "mmio_access" to match the other MMIO cache members and to make it more obvious that it's tracking the access permissions for the MMIO cache.
