[PATCH 0/3] PCI: P2P bridge window fixes

[Bjorn Helgaas]

Two fixes here:

1) Zero is a legal P2P bridge window base and BAR value and is likely to
occur when there is an offset between bus addresses and CPU addresses.
Stop disallowing it.

2) The Intel-specific 1K I/O window granularity for P2P bridges was
implemented in a way that precluded reassignment of the window after
FINAL quirks.  Fix that.

And also replace the sparc pci_cfg_fake_ranges() with the functionally
equivalent generic version.

Bjorn Helgaas (3):
      PCI: allow P2P bridge windows starting at PCI bus address zero
      PCI: reimplement P2P bridge 1K I/O windows (Intel P64H2)
      sparc/PCI: replace pci_cfg_fake_ranges() with pci_read_bridge_bases()
