Subject[patch 25/60] KVM: VMX: Force vm86 mode if setting flags during real mode
2.6.23-stable review patch.  If anyone has any objections, please let us
know.

------------------
From: Avi Kivity <avi@qumranet.com>
patch 78f7826868da8e27d097802139a3fec39f47f3b8 in mainline.

When resetting from userspace, we need to handle the flags being cleared
even after we are in real mode.
