[ Upstream commit 8873aab8646194a4446117bb617cc71bddda2dee ] All these commands end up peeking into the PACA using the user originated cpu id as an index. Check the cpu id is valid in order to prevent xmon to crash. Instead of printing an error, this follows the same behavior as the "lp s #" command : ignore the buggy cpu id parameter and fall back to the #-less version of the command.

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.
