Victor Sun 363daf6aa2 HV: return extended info in vCPUID leaf 0x40000001
In some case, guest need to get more information under virtual environment,
like guest capabilities. Basically this could be done by hypercalls, but
hypercalls are designed for trusted VM/SOS VM, We need a machenism to report
these information for normal VMs. In this patch, vCPUID leaf 0x40000001 will
be used to satisfy this needs that report some extended information for guest
by CPUID.

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.
