If user does not enable kexec or hotplug, these codes are redundant.
So use CONFIG_KEXEC and CONFIG_HOTPLUG_CPU to gard them.

My point is that these lists tend to grow and be a maintenance pain.
For small things it's often better to not worry about saving a few
bytes.  For larger things that need to be conditional, define a new
symbol rather than growing ORed lists like this.

I agree with you in principle. But there are only two config options
in this patch, and it is unlikely to grow. 

That's what everybody says when these things start. :-)
