From bc397a6c914c75d8ae21dad23eba9ae82e34dad3 Mon Sep 17 00:00:00 2001 From: Nadav Amit Date: Wed, 10 Dec 2014 11:19:03 +0200 Subject: [PATCH] KVM: x86: Do not push eflags.vm on pushf The pushf instruction does not push eflags.VM, so emulation should not do so as well. Although eflags.RF should not be pushed as well, it is already cleared by the time pushf is executed.
