Bin Meng d0c9606b31 PCI: Add Device IDs for Intel GPU "spurious interrupt" quirk
Add Device IDs to the Intel GPU "spurious interrupt" quirk table.

For these devices, unplugging the VGA cable and plugging it in again causes
spurious interrupts from the IGD.  Linux eventually disables the interrupt,
but of course that disables any other devices sharing the interrupt.

The theory is that this is a VGA BIOS defect: it should have disabled the
IGD interrupt but failed to do so.

See f67fd55fa9 ("PCI: Add quirk for still enabled interrupts on Intel
Sandy Bridge GPUs") and 7c82126a94 ("PCI: Add new ID for Intel GPU
"spurious interrupt" quirk") for some history.

[bhelgaas: See link below for discussion about how to fix this more
generically instead of adding device IDs for every new Intel GPU.  I hope
this is the last patch to add device IDs.]

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
