Binbin Wu f32b59d73d hv: disable mpx capability for guest 
This patch hide Memory Protection Extention (MPX) capability from guest.

- vCPUID change:
  Clear cpuid.07H.0.ebx[14]
  Clear cpuid.0DH.0.eax[4:3]
- vMSR change:
  Add MSR_IA32_BNDCFGS to un-supported MSR array.
- XCR0[4:3] is not allowed to set by guest.

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.
