Fei Li 6b32b28e72 hv: ptdev: address vector scalability problem by interrupt posting
Now interrupt vector in ACRN hypervisor is maintained as global variable, not
per-CPU variable. If there're more PCI devices, the physical interrupt vectors
are not enough most likely.

This patch would not allocate physical interrupt vector for MSI/MSI-X vectors
if interrupt posting could been used to inject the MSI/MSI-X interrupt to
a VM directly.

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.
