hang and lockup detection menu

The hard/softlockup and hung-task entries take up 6 lines
of screen real-estate when enabled.  I bet folks don't
mess with these _that_ often, so move them in a group
down a level.

Merge branch 'kconfig-diet' from Dave Hansen

Merge Kconfig menu diet patches from Dave Hansen:
 "I think the "Kernel Hacking" menu has gotten a bit out of hand.  It is
  over 120 lines long on my system with everything enabled and options
  are scattered around it haphazardly.

        http://sr71.net/~dave/linux/kconfig-horror.png

  Let's try to introduce some sanity.  This set takes that 120 lines
  down to 55 and makes it vastly easier to find some things.  It's a
  start.

  This set stands on its own, but there is plenty of room for follow-up
  patches.  The arch-specific debug options still end up getting stuck
  in the top-level "kernel hacking" menu.  OPTIMIZE_INLINING, for
  instance, could obviously go in to the "compiler options" menu, but
  the fact that it is defined in arch/ in a separate Kconfig file keeps
  it on its own for the moment.

  The Signed-off-by's in here look funky.  I changed employers while
  working on this set, so I have signoffs from both email addresses"

Limit allocation of crypto mechanisms to dialect which requires

Updated patch to try to prevent allocation of cifs, smb2 or smb3 crypto
secmech structures unless needed.  Currently cifs allocates all crypto
mechanisms when the first session is established (4 functions and
4 contexts), rather than only allocating these when needed (smb3 needs
two, the rest of the dialects only need one).

[CIFS] use sensible file nlink values if unprovided

Certain servers may not set the NumberOfLinks field in query file/path
info responses. In such a case, cifs_inode_needs_reval() assumes that
all regular files are hardlinks and triggers revalidation, leading to
excessive and unnecessary network traffic.

This change hardcodes cf_nlink (and subsequently i_nlink) when not
returned by the server, similar to what already occurs in cifs_mkdir().

  One note on the above.  The binding changes going in from all kinds of

  during this cycle, but even going though my tree isn't a great fit.

  Ian Campbell has prototyped splitting the bindings and .dtb files into
