3.8.13.5 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Gavin Shan <[email protected]> commit 5fb621698e94e3af8b413d9439041fde48e2784d upstream. While running Linux as guest on top of phyp, we possiblly have PE that includes single PCI device. However, we didn't return its PCI bus correctly and it leads to failure on recovery from EEH errors for single-dev-PE. The patch fixes the issue.
