Zide Chen 3691e305c0 hv: dynamically configure CPU affinity through hypercall
- add a new member cpu_affinity to struct acrn_create_vm, so that acrn-dm
  is able to assign CPU affinity through HC_CREATE_VM hypercall.

- if vm_create.cpu_affinity is zero, hypervisor launches the VM with the
  statically configured CPU affinity.

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.
