commit d2b3c353595a855794f8b9df5b5bdbe8deb0c413 upstream. Guenter Roeck reported an interrupt storm on a prototype system which is based on Cyan Chromebook. The root cause turned out to be a incorrectly configured pin that triggers spurious interrupts. This will be fixed in coreboot but currently we need to prevent the interrupt storm from happening by masking all interrupts (but not GPEs) on those systems.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
