From: Changbin Du

This series is a trivial improvment for the layout of 'kernel hacking'
configuration menu. Now we have many items in it which makes takes
a little time to look up them since they are not well structurized yet.

Early discussion is here:

This is a preview:

o rebase to linux-next.
o move DEBUG_FS to 'Generic Kernel Debugging Instruments'
o move DEBUG_NOTIFIERS to 'Debug kernel data structures'
