Lukas Wunner 5ff676fc9e PCI/AER: Support errors introduced by PCIe r6.0
commit 6633875250 upstream.

PCIe r6.0 defined five additional errors in the Uncorrectable Error
Status, Mask and Severity Registers (PCIe r7.0 sec 7.8.4.2ff).

lspci has been supporting them since commit 144b0911cc0b ("ls-ecaps:
extend decode support for more fields for AER CE and UE status"):

  https://git.kernel.org/pub/scm/utils/pciutils/pciutils.git/commit/?id=144b0911cc0b

Amend the AER driver to recognize them as well, instead of logging them as
"Unknown Error Bit".

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 reStructuredText 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.
