Re: [PATCH] Use pid_t instead of int

["René Nyffenegger" <mail-gLCNRsNSrVdVZEhyV+6z5nIPMjoJpjVV@public.gmane.org>]

From: René Nyffenegger <mail-gLCNRsNSrVdVZEhyV+6z5nIPMjoJpjVV@public.gmane.org>

In include/linux/syscalls.h, the four functions sys_kill, sys_tgkill,
sys_tkill and sys_rt_sigqueueinfo are declared with "int pid" and
"int tgid".

However, in kernel/signal.c, the corresponding definitions use
the more appropriate "pid_t" (which is a typedef'd int).

This patch changes "int" to "pid_t" in the declarations of
sys_kill, sys_tgkill, sys_tkill and sys_rt_sigqueueinfo in
include/linux/syscalls.h in order to harmonize the function
declarations with their respective definitions.
