Subject: [PATCH 40/58] panic: Add prototype for __weak stub of panic_smp_self_stop

kernel/panic.c defines an empty stub of panic_smp_self_stop with __weak,
for use on architectures without an alternate implementation.  Define a
prototype of that function, to satisfy gcc (-Wmissing-prototypes) and
Sparse (-Wdecl).

kernel/panic.c:55:28: warning: no previous prototype for ‘panic_smp_self_stop’ [-Wmissing-prototypes]
