From 8a76d7f25f8f24fc5a328c8e15e4a7313cf141b9 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Mon, 4 Apr 2011 12:39:27 +0200 Subject: KVM: x86: Add x86 callback for intercept check This patch adds a callback into kvm_x86_ops so that svm and vmx code can do intercept checks on emulated instructions.
