[PATCH 13/20] mips: add missing declarations

Arnd Bergmann

These are three more functions that are only called from assembler and
only need a declaration to avoid the -Wmissing-prototypes warnings:

arch/mips/kernel/signal.c:904:17: error: no previous prototype for 'do_notify_resume' [-Werror=missing-prototypes]
arch/mips/kernel/traps.c:370:6: error: no previous prototype for 'show_registers' [-Werror=missing-prototypes]
arch/mips/kernel/smp.c:352:17: error: no previous prototype for 'start_secondary' [-Werror=missing-prototypes]
