Today SError is taken using the inv_entry macro that ends up in bad_mode. SError can be used by the RAS Extensions to notify either the OS or firmware of CPU problems, some of which may have been corrected. To allow this handling to be added, add a do_serror() C function that just panic()s. Add the entry.S boiler plate to save/restore the CPU registers and unmask debug exceptions. Future patches may change do_serror() to return if the SError Interrupt was notification of a corrected error.

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.
