Subject: [PATCH 09/10] KVM: VMX: Force vm86 mode if setting flags during real mode
Date: Sun, 2 Dec 2007 13:18:46 +0200 [thread overview]
Message-ID: <11965943271441-git-send-email-avi@qumranet.com> (raw)
In-Reply-To: <1196594327338-git-send-email-avi@qumranet.com>
When resetting from userspace, we need to handle the flags being cleared
even after we are in real mode.
