Subject: [PATCH 45/46] kernel: Move prototype declaration to header file
 include/linux/sched.h from init/main.c

Add prototype declaration of function to header file
include/linux/sched.h from init/main.c because it is used by more than
one file.

This eliminates the following warning in kernel/fork.c:
kernel/fork.c:252:13: warning: no previous prototype for ‘fork_init’ [-Wmissing-prototypes]
