The compressed boot function error() is used to halt execution, but it wasn't marked with "noreturn". This fixes that in preparation for supporting kernel FORTIFY_SOURCE, which uses the noreturn annotation on panic, and calls error(). GCC would warn about a noreturn function calling a non-noreturn function: arch/x86/boot/compressed/misc.c: In function ‘fortify_panic’: arch/x86/boot/compressed/misc.c:416:1: warning: ‘noreturn’ function does return } ^ Signed-off-by: Kees Cook <keescook@chromium.org> Cc: Daniel Micay <danielmicay@gmail.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: H.

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.
