From 022a93080c269e913793bea3a9a7fed06ca7d29b Mon Sep 17 00:00:00 2001 From: Dor Laor Date: Fri, 5 Jan 2007 16:37:00 -0800 Subject: [PATCH] [PATCH] KVM: Simplify test for interrupt window No need to test for rflags.if as both VT and SVM specs assure us that on exit caused from interrupt window opening, 'if' is set.
