Add a simple NMI IPI system that handles concurrency and reentrancy. The platform does not have to implement a true non-maskable interrupt, the default is to simply use the debugger break IPI message. This has now been co-opted for a general IPI message, and users (debugger and crash) have been reimplemented on top of the NMI system.

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.
