Hello all,

This is next version of vPCI rework. Aim of this series is to prepare
ground for introducing PCI support on ARM platform.

This vesion includes addressed commentes from a previous one. Also it
introduces a couple patches from Stewart. This patches are related to
vPCI use on ARM. Patch "vpci/header: rework exit path in init_bars"
was factored-out from "vpci/header: handle p2m range sets per BAR".

Changes from previous versions are described in each separate patch.

Oleksandr Andrushchenko (12):
  vpci: use per-domain PCI lock to protect vpci structure
  vpci: restrict unhandled read/write operations for guests
  vpci: add hooks for PCI device assign/de-assign
  vpci/header: implement guest BAR register handlers
  rangeset: add RANGESETF_no_print flag
  vpci/header: handle p2m range sets per BAR
  vpci/header: program p2m with guest BAR view
  vpci/header: emulate PCI_COMMAND register for guests
  vpci/header: reset the command register when adding devices
  vpci: add initial support for virtual PCI bus topology
  xen/arm: translate virtual PCI bus topology for guests
  xen/arm: account IO handlers for emulated PCI MSI-X

Stewart Hildebrand (2):
  xen/arm: vpci: check guest range
  xen/arm: vpci: permit access to guest vpci space

Volodymyr Babchuk (2):
  pci: introduce per-domain PCI rwlock
  vpci/header: rework exit path in init_bars
