Add support for handling AER errors detected by Root Complex Integrated Endpoints (RCiEPs). These errors are signaled to software natively via a Root Complex Event Collector (RCEC) or non-natively via ACPI APEI if the platform retains control of AER or uses a non-standard RCEC-like device. When recovering from RCiEP errors, the Root Error Command and Status registers are in the AER Capability of an associated RCEC (if any), not in a Root Port. In the non-native case, the platform is responsible for those registers and we can't touch them.

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.
