[PATCH] kernel/sys.c: cleanups
- proper prototypes for the following functions: - ctrl_alt_del() (in include/linux/reboot.h) - getrusage() (in include/linux/resource.h) - make the following needlessly global functions static: - kernel_restart_prepare() - kernel_kexec() [akpm@osdl.org: compile fix] Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
