      sched: numa: Fix build error if CONFIG_NUMA_BALANCING && !CONFIG_TRANSPARENT_HUGEPAGE · 221392c3
      Mel Gorman authored
      Michal Hocko reported that the following build error occurs if
      CONFIG_NUMA_BALANCING is set without THP support
      
        kernel/sched/fair.c: In function ‘task_numa_work’:
        kernel/sched/fair.c:932:55: error: call to ‘__build_bug_failed’ declared with attribute error: BUILD_BUG failed
      
      The problem is that HPAGE_PMD_SHIFT triggers a BUILD_BUG() on
      !CONFIG_TRANSPARENT_HUGEPAGE. This patch addresses the problem.

      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.

      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.

        The second new feature is SEEK_HOLE/SEEK_DATA support.  This is

      ARM: OMAP: Fix drivers to depend on omap for internal devices · 770b6cb4
      Tony Lindgren authored
      These devices are not available on other architectures, so
      let's limit them to omap.
      
      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."

      Include the entire kernel memory map in trampoline_pgd") that got
      reverted earlier due to the problems it caused.
      
      This was pointed out by Yinghai Lu, and verified by me on my Macbook Air
      that uses EFI.

      Pull target updates from Nicholas Bellinger:
       "It has been a very busy development cycle this time around in target
        land, with the highlights including:
      
         - Kill struct se_subsystem_dev, in favor of direct se_device usage
           (hch)
         - Simplify reservations code by combining SPC-3 + SCSI-2 support for
           virtual backends only (hch)
         - Simplify ALUA code for virtual only backends, and remove left over
           abstractions (hch)
         - Pass sense_reason_t as return value for I/O submission path (hch)
         - Refactor MODE_SENSE emulation to allow for easier addition of new
           mode pages.  (roland)
         - Add emulation of MODE_SELECT (roland)
         - Fix bug in handling of ExpStatSN wrap-around (steve)
         - Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve)
         - Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab)
         - Convert ib_srpt to use modern target_submit_cmd caller + drop
           legacy ioctx->kref usage (nab)
         - Convert ib_srpt to use modern target_submit_tmr caller (nab)
         - Add link_magic for fabric allow_link destination target_items for
           symlinks within target_core_fabric_configfs.c code (nab)
         - Allocate pointers in instead of full structs for
           config_group->default_groups (sebastian)
         - Fix 32-bit highmem breakage for FILEIO (sebastian)
      
        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.
      
        Thank you again to everyone who contributed this round!"

      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.

      Smack: use select not depends in Kconfig · 111fe8bd
      Casey Schaufler authored
      The components NETLABEL and SECURITY_NETWORK are required by
      Smack. Using "depends" in Kconfig hides the Smack option
      if the user hasn't figured out that they need to be enabled
      while using make menuconfig. Using select is a better choice.
      Because select is not recursive depends on NET and SECURITY
      are added. The reflects similar usage in TOMOYO and AppArmor.

      Pull x86 ACPI update from Peter Anvin:
       "This is a patchset which didn't make the last merge window.  It adds a
        debugging capability to feed ACPI tables via the initramfs.
      
        On a grander scope, it formalizes using the initramfs protocol for
        feeding arbitrary blobs which need to be accessed early to the kernel:
        they are fed first in the initramfs blob (lots of bootloaders can
        concatenate this at boot time, others can use a single file) in an
        uncompressed cpio archive using filenames starting with "kernel/".
      
        The ACPI maintainers requested that this patchset be fed via the x86
        tree rather than the ACPI tree as the footprint in the general x86
        code is much bigger than in the ACPI code proper."

      Linus Torvalds authored
      This reverts commit f269ae04.
      
      It turns out it causes a very noticeable interactivity regression with
      CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a
      terminal window, while scrolling in a browser - the autogrouping means
      that the two end up in separate cgroups, and the browser should be
      smooth as silk despite the high load).
      
      Says Paul Turner:
       "It seems that the update-throttling on the wake-side is reducing the
        interactive tasks' ability to preempt.  While I suspect the right
        longer term answer here is force these updates only in the
        cross-cgroup case; this is less trivial.  For this release I believe
        the right answer is either going to be a revert or restore the updates
        on the enqueue-side."
