This patch (or some successor version of it) showed up
in next-20140317 and the above declaration caused a
bunch of warnings on ia64:

include/linux/sched.h:1718: warning: 'pid_alive' declared inline after
being called

[repeated 1675 times across files that include this]

The ia64 complier is a lot happier if "inline" is added like this:

static inline int pid_alive(const struct task_struct *p);
