From 25391454e73e3156202264eb3c473825afe4bc94 Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Mon, 21 Jan 2013 15:36:46 +0200 Subject: [PATCH] KVM: VMX: don't clobber segment AR of unusable segments. Usability is returned in unusable field, so not need to clobber entire AR. Callers have to know how to deal with unusable segments already since if emulate_invalid_guest_state=true AR is not zeroed.
