From a83b29c6ad6d6497e569edbc29e556a384cebddd Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Thu, 10 Jun 2010 17:02:15 +0300 Subject: KVM: Fix mov cr4 #GP at wrong instruction On Intel, we call skip_emulated_instruction() even if we injected a #GP, resulting in the #GP pointing at the wrong address. Fix by injecting the exception and skipping the instruction at the same place, so we can do just one or the other.
