      Pull block layer core updates from Jens Axboe:
       "Here are the core block IO bits for 3.8.  The branch contains:
      
         - The final version of the surprise device removal fixups from Bart.
      
         - Don't hide EFI partitions under advanced partition types.  It's
           fairly wide spread these days.  This is especially dangerous for
           systems that have both msdos and efi partition tables, where you
           want to keep them in sync.
      
         - Cleanup of using -1 instead of the proper NUMA_NO_NODE
      
         - Export control of bdi flusher thread CPU mask and default to using
           the home node (if known) from Jeff.
      
         - Export unplug tracepoint for MD.
      
         - Core improvements from Shaohua.  Reinstate the recursive merge, as
           the original bug has been fixed.  Add plugging for discard and also
           fix a problem handling non pow-of-2 discard limits.
      
        There's a trivial merge in block/blk-exec.c due to a fix that went
        into 3.7-rc at a later point than -rc4 where this is based."

      mm: fix kernel BUG at huge_memory.c:1474! · a4f1de17
      Hugh Dickins authored
      Andrea's autonuma-benchmark numa01 hits kernel BUG at huge_memory.c:1474!
      in change_huge_pmd called from change_protection from change_prot_numa
      from task_numa_work.
      
      That BUG, introduced in the huge zero page commit cad7f613 ("thp:
      change_huge_pmd(): make sure we don't try to make a page writable")
      was trying to verify that newprot never adds write permission to an
      anonymous huge page; but Automatic NUMA Balancing's 4b10e7d5 ("mm:
      mempolicy: Implement change_prot_numa() in terms of change_protection()")
      adds a new prot_numa path into change_huge_pmd(), which makes no use of
      the newprot provided, and may retain the write bit in the pmd.
      
      Just move the BUG_ON(pmd_write(entry)) up into the !prot_numa block.

      Linus Torvalds authored
      Pull MFS update from Samuel Ortiz:
       "This is the MFD patch set for the 3.8 merge window.
      
        We have several new drivers, most of the time coming with their sub
        devices drivers:
      
         - Austria Microsystem's AS3711
         - Nano River's viperboard
         - TI's TPS80031, AM335x TS/ADC,
         - Realtek's MMC/memstick card reader
         - Nokia's retu
      
        We also got some notable cleanups and improvements:
      
         - tps6586x got converted to IRQ domains.
         - tps65910 and tps65090 moved to the regmap IRQ API.
         - STMPE is now Device Tree aware.
         - A general twl6040 and twl-core cleanup, with moves to the regmap
           I/O and IRQ APIs and a conversion to the recently added PWM
           framework.
         - sta2x11 gained regmap support.
      
        Then the rest is mostly tiny cleanups and fixes, among which we have
        Mark's wm5xxx and wm8xxx patchset."
      
      Far amount of annoying but largely trivial conflicts.  Many due to
      __devinit/exit removal, others due to one or two of the new drivers also
      having come in through another tree.

      If the driver subsystem maintainers want to build test
      system wide changes without building for each target,
      it's easy to carry a test patch that just strips out the
      depends entries from Kconfig files.

      Pull Automatic NUMA Balancing bare-bones from Mel Gorman:
       "There are three implementations for NUMA balancing, this tree
        (balancenuma), numacore which has been developed in tip/master and
        autonuma which is in aa.git.
      
        In almost all respects balancenuma is the dumbest of the three because
        its main impact is on the VM side with no attempt to be smart about
        scheduling.  In the interest of getting the ball rolling, it would be
        desirable to see this much merged for 3.8 with the view to building
        scheduler smarts on top and adapting the VM where required for 3.9.
      
        The most recent set of comparisons available from different people are
      
          mel:    https://lkml.org/lkml/2012/12/9/108
          mingo:  https://lkml.org/lkml/2012/12/7/331
          tglx:   https://lkml.org/lkml/2012/12/10/437
          srikar: https://lkml.org/lkml/2012/12/10/397
      
        The results are a mixed bag.  In my own tests, balancenuma does
        reasonably well.  It's dumb as rocks and does not regress against
        mainline.  On the other hand, Ingo's tests shows that balancenuma is
        incapable of converging for this workloads driven by perf which is bad
        but is potentially explained by the lack of scheduler smarts.  Thomas'
        results show balancenuma improves on mainline but falls far short of
        numacore or autonuma.  Srikar's results indicate we all suffer on a
        large machine with imbalanced node sizes.
      
        My own testing showed that recent numacore results have improved
        dramatically, particularly in the last week but not universally.
        We've butted heads heavily on system CPU usage and high levels of
        migration even when it shows that overall performance is better.
        There are also cases where it regresses.  Of interest is that for
        specjbb in some configurations it will regress for lower numbers of
        warehouses and show gains for higher numbers which is not reported by
        the tool by default and sometimes missed in treports.  Recently I
        reported for numacore that the JVM was crashing with
        NullPointerExceptions but currently it's unclear what the source of
        this problem is.  Initially I thought it was in how numacore batch
        handles PTEs but I'm no longer think this is the case.  It's possible
        numacore is just able to trigger it due to higher rates of migration.
      
        These reports were quite late in the cycle so I/we would like to start
        with this tree as it contains much of the code we can agree on and has
        not changed significantly over the last 2-3 weeks."

      Also drop the reference to 2 command byte I2C block reads, there is no

        All told, hch was able to shave off another ~1K LOC by killing the
        se_subsystem_dev abstraction, along with a number of PR + ALUA
        simplifications.  Also, a nice patch by Roland is the refactoring of
        MODE_SENSE handling, along with the addition of initial MODE_SELECT
        emulation support for virtual backends.
      
        Sebastian found a long-standing issue wrt to allocation of full
        config_group instead of pointers for config_group->default_group[]
        setup in a number of areas, which ends up saving memory with big
        configurations.  He also managed to fix another long-standing BUG wrt
        to broken 32-bit highmem support within the FILEIO backend driver.

      Pull GFS2 updates from Steven Whitehouse:
       "The main feature this time is the new Orlov allocator and the patches
        leading up to it which allow us to allocate new inodes from their own
        allocation context, rather than borrowing that of their parent
        directory.  It is this change which then allows us to choose a
        different location for subdirectories when required.  This works
        exactly as per the ext3 implementation from the users point of view.
      
        In addition to that, we've got a speed up in gfs2_rbm_from_block()
        from Bob Peterson, three locking related improvements from Dave
        Teigland plus a selection of smaller bug fixes and clean ups."

      Linus Torvalds authored
      This reverts commit 53b87cf0.
      
      It causes odd bootup problems on x86-64.  Markus Trippelsdorf gets a
      repeatable oops, and I see a non-repeatable oops (or constant stream of
      messages that scroll off too quickly to read) that seems to go away with
      this commit reverted.
      
      So we don't know exactly what is wrong with the commit, but it's
      definitely problematic, and worth reverting sooner rather than later.
