Subject: [PATCH 37/58] kernel/fork.c: Add prototype for fork_init

kernel/fork.c defines an __init function fork_init, called from
init/main.c.  No header file prototypes fork_init, because init/main.c
tends to directly define prototypes for init functions it calls, rather
than including appropriate headers.  So, add a prototype of fork_init to
kernel/fork.c right above the definition, to satisfy gcc
(-Wmissing-prototypes) and Sparse (-Wdecl).

kernel/fork.c:251:116: warning: no previous prototype for ‘fork_init’ [-Wmissing-prototypes]
