    Subject[PATCH] ARM: quiet sparse noise due to __ARCH_WANT_SYS_RT_SIG(ACTION|SUSPEND)
    produces the following sparse warnings in kernel/signal.c:

    warning: symbol 'sys_rt_sigaction' was not declared. Should it be static?
    warning: symbol 'sys_rt_sigsuspend' was not declared. Should it be static?

    Since ARM doesn't include <asm-generic/syscalls.h>, due to different
    calling conventions for some system calls, prototype the functions
    in <asm/unistd.h> to quiet the noise.
