      Merge branch 'kconfig-diet' from Dave Hansen · e61aca51

      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"

      Again, trying to come up with some common themes of the stuff in
      the kernel hacking menu...  There are quite a few options to
      tweak compilation in some way, or perform extra compile-time
      checks.  Give them their own menu.
      
      The diff here looks a bit funny... makes it look like I'm
      moving debugfs even though I'm actually moving the options on
      either side of it.

      These runtime tests are great, except that there are a lot of them,
      and they are very rarely needed.  Give them their own menu so that
      only the folks who need them will have to go looking for them.
      
      Note that there are some other runtime tests that are not in here,
      like for RCU or locking.  This menu should only be used for tests
      that do not have a more appropriate home.

      There are a *LOT* of memory debugging options.  They are just scattered
      all over the "Kernel Hacking" menu.  Sure, "memory debugging" is a very
      vague term and it's going to be hard to make absolute rules about what
      goes in here, but this has to be better than what we had before.
      
      This does, however, leave out the architecture-specific memory
      debugging options (like x86's DEBUG_SET_MODULE_RONX).  There would need
      to be some substantial changes to move those in here.  Kconfig can not
      easily mix arch-specific and generic options together: it really
      requires a file per-architecture, and I think having an
      arch/foo/Kconfig.debug-memory might be taking things a bit too far

      Several architectures have similar stack debugging config options.
      They all pretty much do the same thing, some with slightly
      differing help text.
      
      This patch changes the architectures to instead enable a Kconfig
      boolean, and then use that boolean in the generic Kconfig.debug
      to present the actual menu option.  This removes a bunch of
      duplication and adds consistency across arches.

      The test if bitmap access is out of bound could errorneously pass if the
      device size is divisible by 16384 sectors and we are asking for one bitmap
      after the end.
      
      Check for invalid size in the superblock. Invalid size could cause integer
      overflows in the rest of the code.

      Pull powerpc updates from Ben Herrenschmidt:
       "This is the powerpc changes for the 3.11 merge window.  In addition to
        the usual bug fixes and small updates, the main highlights are:
      
         - Support for transparent huge pages by Aneesh Kumar for 64-bit
           server processors.  This allows the use of 16M pages as transparent
           huge pages on kernels compiled with a 64K base page size.
      
         - Base VFIO support for KVM on power by Alexey Kardashevskiy
      
         - Wiring up of our nvram to the pstore infrastructure, including
           putting compressed oopses in there by Aruna Balakrishnaiah
      
         - Move, rework and improve our "EEH" (basically PCI error handling
           and recovery) infrastructure.  It is no longer specific to pseries
           but is now usable by the new "powernv" platform as well (no
           hypervisor) by Gavin Shan.
      
         - I fixed some bugs in our math-emu instruction decoding and made it
           usable to emulate some optional FP instructions on processors with
           hard FP that lack them (such as fsqrt on Freescale embedded
           processors).
      
         - Support for Power8 "Event Based Branch" facility by Michael
           Ellerman.  This facility allows what is basically "userspace
           interrupts" for performance monitor events.
      
         - A bunch of Transactional Memory vs.  Signals bug fixes and HW
           breakpoint/watchpoint fixes by Michael Neuling.
      
        And more ...  I appologize in advance if I've failed to highlight
        something that somebody deemed worth it."
