From 4a4c99248713e878e1e2880015d01049aec805f3 Mon Sep 17 00:00:00 2001 From: Anthony Liguori Date: Wed, 10 Oct 2007 20:08:41 -0500 Subject: [PATCH] KVM: MMU: More struct kvm_vcpu -> struct kvm cleanups This time, the biggest change is gpa_to_hpa. The translation of GPA to HPA does not depend on the VCPU state unlike GVA to GPA so there's no need to pass in the kvm_vcpu.
