Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".
In other words, we are adopting the same practice in Linux kernel.

Add a new field 'parent_user' to record the parent user of the vdev. And refine
'new_owner' to 'user' to record who is the current user of the vdev. Like

vdev in | HV | pre-VM | SOS | post-VM
| | |vdev used by SOS|vdev used by post-VM|

add vpci bridge operations in hypervisor, to avoid SOS mis-operations
to affect other VM's PCI devices.
assumption: before hypervisor bootup, the physical pci-bridge shall be
configured correctly by BIOS or other bootloader; for ACS (Access
Control Service) capability, it is configured by BIOS to support the
devices under it to be isolated and allocated to different VMs.
to simplify the emulations of vpci bridge, set limitations as following:
1. expose all configure space registers, but readonly
2. BIST not support; by default is 0
3. not support interrupt, including INTx and MSI.
TODO:
1. configure tool can select whether a PCI bridge is emulated or pass
through.
Open:
1. SOS how to reset PCI device under the PCI bridge?
