Kai-Heng Feng d41fcaa12a PCI/AER: Disable AER service on suspend
[ Upstream commit 5afc2f763edc5daae4722ee46fea4e627d01fa90 ]

If the link is powered off during suspend, electrical noise may cause
errors that are logged via AER.  If the AER interrupt is enabled and shares
an IRQ with PME, that causes a spurious wakeup during suspend.

Disable the AER interrupt during suspend to prevent this.  Clear error
status before re-enabling IRQ interrupts during resume so we don't get an
interrupt for errors that occurred during the suspend/resume process.

README

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.
