From 6fec21449a62702a582cecbb0b351363e039c95e Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 22 Sep 2015 23:02:14 +0200 Subject: [PATCH] KVM: x86: use correct page table format to check nested page table reserved bits Intel CPUID on AMD host or vice versa is a weird case, but it can happen. Handle it by checking the host CPU vendor instead of the guest's in reset_tdp_shadow_zero_bits_mask. For speed, the check uses the fact that Intel EPT has an X (executable) bit while AMD NPT has NX.
