Yu Wang 7f2b9a1c7d hv: virq: update apicv irr/rvi before handle vmcs event injection
From SDM Vol3 26.3.2.5:
Once the virtual interrupt is recognized, it will be delivered in VMX
non-root operation immediately after VM entry(including any specified
event injection) completes.

So the hardware can handle vmcs event injection and evaluation/delivery
of apicv virtual interrupts in one time vm-entry.

This patch move the apicv irr/rvi sync before handle vmcs events
injection. The old code cause the apicv virtual interrupt evaluation and
delivery be handled until next vm-exit if met pending exceptions.

Embedded-Hypervisor
###################

This open source embedded hypervisor defines a software architecture for
running multiple software subsystems managed securely on a consolidated
system (by means of a virtual machine manager), and defines a reference
framework Device Model implementation for devices emulation

This embedded hypervisor is type-1 reference hypervisor, running
directly on the system hardware. It can be used for building software
defined cockpit (SDC) or In-Vehicle Experience (IVE) solutions running
on Intel Architecture Apollo Lake platforms. As a reference
implementation, it provides the basis for embedded hypervisor vendors to
build solutions with an open source reference I/O mediation solution,
and provides auto makers a reference software stack for SDC usage.

This embedded hypervisor is able to support both Linux* and Android* as
a Guest OS, managed by the hypervisor, where applications can run.

This embedded hypervisor is a partitioning hypervisor reference stack,
also suitable for non-automotive IoT & embedded device solutions. It
will be addressing the gap that currently exists between datacenter
hypervisors, hard partitioning hypervisors, and select industrial
applications.  Extending the scope of this open source embedded
hypervisor relies on the involvement of community developers like you!
