Sorry for that. it should have mentioned the kernel folder instead of
lib. But I think it won't clarify the above.

In any case there are several purposes in this case
 - dropping dependency in bug.h
 - dropping a loop by moving out panic_notifier.h
 - unload kernel.h from something which has its own domain

I think that you are referring to the commit message describing 3rd
one, but not 1st and 2nd.

I will amend this for the future splits, thanks!
