ARM: 9309/1: add missing syscall prototypes
All architecture-independent system calls have prototypes in
include/linux/syscalls.h, but there are a few that only exist
on arm or that take the pt_regs directly. These cause a W=1
warning such as:
arch/arm/kernel/signal.c:186:16: error: no previous prototype for 'sys_sigreturn' [-Werror=missing-prototypes]
arch/arm/kernel/signal.c:216:16: error: no previous prototype for 'sys_rt_sigreturn' [-Werror=missing-prototypes]
arch/arm/kernel/sys_arm.c:32:17: error: no previous prototype for 'sys_arm_fadvise64_64' [-Werror=missing-prototypes]
Add prototypes for all custom syscalls on arm and add them
to asm/syscalls.h.
