Remove the WARNING message associated with multiple NMI handlers as there are at least two that are legitimate. These are the KGDB and the UV handlers and both want to be called if the NMI has not been claimed by any other NMI handler. Use of the UNKNOWN NMI call chain dramatically lowers the NMI call rate when high frequency NMI tools are in use, notably the perf tools. It is required on systems that cannot sustain a high NMI call rate without adversely affecting the system operation.

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.
