[PATCH for-4.17 0/6] (v)pci: fixes related to memory decoding handling

[Roger Pau Monne <roger.pau@citrix.com>]

Hello,

First two patches fix some build isses that showed up on the vpci test
harness, following patches attempt to fix the regressions caused by
75cc460a1b ('xen/pci: detect when BARs are not suitably positioned') and
the last patch relaxes the check done when attempting to write to BARs
with memory decoding enabled.

I consider all of them bug fixes, albeit the last patch is not fixing a
regression (since vPCI code has always behaved this way).

Thanks, Roger.

Roger Pau Monne (6):
  test/vpci: add dummy cfcheck define
  test/vpci: fix vPCI test harness to provide pci_get_pdev()
  vpci: don't assume that vpci per-device data exists unconditionally
  vpci: introduce a local vpci_bar variable to modify_decoding()
  pci: do not disable memory decoding for devices
  vpci: refuse BAR writes only if the BAR is mapped
