Why are these "add" and "remove" functions here?  Shouldn't you just
write the lines out where you call them instead, as they are only called
once.

And does this race with adding new cpus to the system (is the uevent
being sent to userspace before the attributes are added?)  If so, please
fix that.

thanks,
