Queued for 3.16.  Thanks Paul & Andreas!

I'll think about it.  The hook is no useful if unused then again now and
then ordering issues in SMP startup of secondary CPUs are showing up and
it may be useful to solve those.  Maybe something like

void __init smp_cpus_done(unsigned int max_cpus)
- 	mp_ops->cpus_done();
+ 	if (cpus_done)
+ 		mp_ops->cpus_done();

which would make a NULL cpus_done function pointer safe and allow empty definitions
to be removed.
