From 2d48a985c7bbcd72b4e92e301ea96bf1252ffc61 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Fri, 10 Sep 2010 17:31:01 +0200 Subject: KVM: MMU: Track NX state in struct kvm_mmu With Nested Paging emulation the NX state between the two MMU contexts may differ. To make sure that always the right fault error code is recorded this patch moves the NX state into struct kvm_mmu so that the code can distinguish between L1 and L2 NX state.
