4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann <arnd@xxxxxxxx> commit 6a32c2469c3fbfee8f25bcd20af647326650a6cf upstream. Building any configuration with 'make W=1' produces a warning: kernel/bounds.c:16:6: warning: no previous prototype for 'foo' [-Wmissing-prototypes] When also passing -Werror, this prevents us from building any other files. Nobody ever calls the function, but we can't make it 'static' either since we want the compiler output. Calling it 'main' instead however avoids the warning, because gcc does not insist on having a declaration for main.
