Subject: [RESEND PATCH v3 0/9] hacking: make kconfig menu 'kernel hacking' better structurized

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:

v3:
  o change subject prefix.
v2:
  o rebase to linux-next.
  o move DEBUG_FS to 'Generic Kernel Debugging Instruments'
  o move DEBUG_NOTIFIERS to 'Debug kernel data structures'
