[PATCH v2 0/9] kconfig/hacking: make 'kernel hacking' menu better structurized

[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:
