Yonghua Huang 4fc5dcfc3e hv: enable SMAP in hypervisor 
With SMAP enabled, hypervisor can't access pages that
owned by guest(either SOS or UOS), and an override is
is provided: stac()/clac() to enable/disable access to
guest's memory pages.

 Pre-conditon:
    Mark hypervisor owned pages as supervisor mode (U/S = 0),
       and set all othter memory pages as user mode (U/S = 1).

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
“ACRN Device Model”.

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
