Li, Fei1 5930e96d12 hv: io_req: refine vhm_req status setting
In spite of vhm_req status could be updated in HV and DM on different CPUs, they
only change vhm_req status when they detect vhm_req status has been updated by
each other. So vhm_req status will not been misconfigured. However, before HV
sets vhm_req status to REQ_STATE_PENDING, vhm_req buffer filling should be visible
to DM. Add a write memory barrier to guarantee this.

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.
