## Overview

In the Linux kernel, the following vulnerability has been resolved:

powerpc/eeh: Make EEH driver device hotplug safe

Multiple race conditions existed between the PCIe hotplug driver and the
EEH driver, leading to a variety of kernel oopses of the same general
nature:

<pcie device unplug>
<eeh driver trigger>
<hotplug removal trigger>
<pcie tree reconfiguration>
<eeh recovery next step>
<oops in EEH driver bus iteration loop>

A second class of oops is also seen when the underlying bus disappears
during device recovery.

Refactor the EEH module to be PCI rescan and remove safe.  Also clean
up a few minor formatting / readability issues.
