[ Upstream commit 1010b4c012b0d78dfb9d3132b49aa2ef024a07a7 ] 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
