Sure, done.

While it is guranteed that this function is never going to be called
once system is booted, and we indeed can unload it. I do not think
this is possible, because this function is called from sched_clock(),
which is not part of __init section. Is there a way to do it and not
to have a warning about section missmatch?

I will send out new patches with Dou's comments addressed soon.

Thank you,
Pavel
