From db1c056cee59f4a7670c3bd9ee1657468cf0b4c4 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 8 Dec 2016 15:31:41 +0100 Subject: [PATCH] kvm: vmx: Use the hardware provided GPA instead of page walk As in the SVM patch, the guest physical address is passed by VMX to x86_emulate_instruction already, so mark the GPA as available in vcpu->arch.
