Subject[PATCH 18/21] powerpc: Add missing prototypes for sys_sigreturn & sys_rt_sigreturn
Date
Two functions did not have a prototype defined in signal.h header. Fix the
following two warnings (treated as errors in W=1):

CC arch/powerpc/kernel/signal_32.o
arch/powerpc/kernel/signal_32.c:1135:6: error: no previous prototype for ‘sys_rt_sigreturn’ [-Werror=missing-prototypes]
long sys_rt_sigreturn(int r3, int r4, int r5, int r6, int r7, int r8,
^~~~~~~~~~~~~~~~
arch/powerpc/kernel/signal_32.c:1422:6: error: no previous prototype for ‘sys_sigreturn’ [-Werror=missing-prototypes]
long sys_sigreturn(int r3, int r4, int r5, int r6, int r7, int r8,
^~~~~~~~~~~~~
cc1: all warnings being treated as errors
