       "Non-critical kbuild changes:
      
         - make coccicheck improvements, but no new semantic patches this time

         - make tar-pkg change to include the architecture in the filename.
      
           This is a deliberate incompatibility, but nobody has complained so
           far and it is useful if you build for different architectures.  It
           also matches what the deb-pkg and rpm-pkg targets produce.

      menuconfig: fix NULL pointer dereference when searching a symbol · 383da76f
      Li Zefan authored
      Searching for PPC_EFIKA results in a segmentation fault, and it's
      because get_symbol_prop() returns NULL.
      
      In this case CONFIG_PPC_EFIKA is defined in arch/powerpc/platforms/
      52xx/Kconfig, so it won't be parsed if ARCH!=PPC, but menuconfig knows
      this symbol when it parses sound/soc/fsl/Kconfig:
      
          config SND_MPC52xx_SOC_EFIKA
              tristate "SoC AC97 Audio support for bbplan Efika and STAC9766"
              depends on PPC_EFIKA
      
      This bug was introduced by commit bcdedcc1
      
       ("menuconfig: print more
      info for symbol without prompts").

      autofs - remove autofs dentry mount check · ce8a5dbd
      David Jeffery authored
      
      
      When checking if an autofs mount point is busy it isn't sufficient to
      only check if it's a mount point.
      
      For example, if the mount of an offset mountpoint in a tree is denied
      for this host by its export and the dentry becomes a process working
      directory the check incorrectly returns the mount as not in use at
      expire.
      
      This can happen since the default when mounting within a tree is
      nostrict, which means ingnore mount fails on mounts within the tree and
      continue.  The nostrict option is meant to allow mounting in this case.

      3c59x: fix freeing nonexistent resource on driver unload · c81400be
      Sergei Shtylyov authored
      
      
      When unloading the driver that drives an EISA board, a message similar to the
      following one is displayed:
      
      Trying to free nonexistent resource <0000000000013000-000000000001301f>
      
      Then an user is unable to reload the driver because the resource it requested in
      the previous load hasn't been freed. This happens most probably due to a typo in
      vortex_eisa_remove() which calls release_region() with 'dev->base_addr'  instead
      of 'edev->base_addr'...

      net: frag, fix race conditions in LRU list maintenance · b56141ab
      Konstantin Khlebnikov authored
      This patch fixes race between inet_frag_lru_move() and inet_frag_lru_add()
      which was introduced in commit 3ef0eb0d
      
      
      ("net: frag, move LRU list maintenance outside of rwlock")
      
      One cpu already added new fragment queue into hash but not into LRU.
      Other cpu found it in hash and tries to move it to the end of LRU.
      This leads to NULL pointer dereference inside of list_move_tail().
      
      Another possible race condition is between inet_frag_lru_move() and
      inet_frag_lru_del(): move can happens after deletion.
      
      This patch initializes LRU list head before adding fragment into hash and
      inet_frag_lru_move() doesn't touches it if it's empty.
      
      I saw this kernel oops two times in a couple of days.

           through i2c or SPI.
      
         - Silicon Laboratories 476x controller, providing access to their FM

         - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based
           reader.
      
         - Nokia's Tahvo power button and watchdog device.  This device is
           very similar to Retu and is thus supported by the same code base.
      
         - STMicroelectronics STMPE1801, a keyboard and GPIO controller
           supported by the stmpe driver.
      
         - ST-Ericsson AB8540 and AB8505 power management and voltage
           converter controllers through the existing ab8500 code.
      
        Some other drivers got cleaned up or improved.  In particular:
      
         - The Linaro/STE guys got the ab8500 driver in sync with their
           internal code through a series of optimizations, fixes and
           improvements.
      
         - The AS3711 and OMAP USB drivers now have DT support.
      
         - The arizona clock and interrupt handling code got improved.

      tcp: do not expire TCP fastopen cookies · efeaa555
      Eric Dumazet authored
      
      
      TCP metric cache expires entries after one hour.
      
      This probably make sense for TCP RTT/RTTVAR/CWND, but not
      for TCP fastopen cookies.
      
      Its better to try previous cookie. If it appears to be obsolete,
      server will send us new cookie anyway.

      net/eth/ibmveth: Fixup retrieval of MAC address · 13f85203
      Benjamin Herrenschmidt authored
      
      
      Some ancient pHyp versions used to create a 8 bytes local-mac-address
      property in the device-tree instead of a 6 bytes one for veth.
      
      The Linux driver code to deal with that is an insane hack which also
      happens to break with some choices of MAC addresses in qemu by testing
      for a bit in the address rather than just looking at the size of the
      property.
      
      Sanitize this by doing the latter instead.

      Merge branch 'timers-nohz-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · 534c97b0
      Linus Torvalds authored
      Pull 'full dynticks' support from Ingo Molnar:
       "This tree from Frederic Weisbecker adds a new, (exciting! :-) core
        kernel feature to the timer and scheduler subsystems: 'full dynticks',
        or CONFIG_NO_HZ_FULL=y.
      
        This feature extends the nohz variable-size timer tick feature from
        idle to busy CPUs (running at most one task) as well, potentially
        reducing the number of timer interrupts significantly.
      
        This feature got motivated by real-time folks and the -rt tree, but
        the general utility and motivation of full-dynticks runs wider than
        that:
      
         - HPC workloads get faster: CPUs running a single task should be able
           to utilize a maximum amount of CPU power.  A periodic timer tick at
           HZ=1000 can cause a constant overhead of up to 1.0%.  This feature
           removes that overhead - and speeds up the system by 0.5%-1.0% on
           typical distro configs even on modern systems.
      
         - Real-time workload latency reduction: CPUs running critical tasks
           should experience as little jitter as possible.  The last remaining
           source of kernel-related jitter was the periodic timer tick.
      
         - A single task executing on a CPU is a pretty common situation,
           especially with an increasing number of cores/CPUs, so this feature
           helps desktop and mobile workloads as well.
      
        The cost of the feature is mainly related to increased timer
        reprogramming overhead when a CPU switches its tick period, and thus
        slightly longer to-idle and from-idle latency.
      
        Configuration-wise a third mode of operation is added to the existing
        two NOHZ kconfig modes:
      
         - CONFIG_HZ_PERIODIC: [formerly !CONFIG_NO_HZ], now explicitly named
           as a config option.  This is the traditional Linux periodic tick
           design: there's a HZ tick going on all the time, regardless of
           whether a CPU is idle or not.
      
         - CONFIG_NO_HZ_IDLE: [formerly CONFIG_NO_HZ=y], this turns off the
           periodic tick when a CPU enters idle mode.
      
         - CONFIG_NO_HZ_FULL: this new mode, in addition to turning off the
           tick when a CPU is idle, also slows the tick down to 1 Hz (one
           timer interrupt per second) when only a single task is running on a
           CPU.
      
        The .config behavior is compatible: existing !CONFIG_NO_HZ and
        CONFIG_NO_HZ=y settings get translated to the new values, without the
        user having to configure anything.  CONFIG_NO_HZ_FULL is turned off by
        default.
      
        This feature is based on a lot of infrastructure work that has been
        steadily going upstream in the last 2-3 cycles: related RCU support
        and non-periodic cputime support in particular is upstream already.
      
        This tree adds the final pieces and activates the feature.  The pull
        request is marked RFC because:
      
         - it's marked 64-bit only at the moment - the 32-bit support patch is
           small but did not get ready in time.
      
         - it has a number of fresh commits that came in after the merge
           window.  The overwhelming majority of commits are from before the
           merge window, but still some aspects of the tree are fresh and so I
           marked it RFC.
      
         - it's a pretty wide-reaching feature with lots of effects - and
           while the components have been in testing for some time, the full
           combination is still not very widely used.  That it's default-off
           should reduce its regression abilities and obviously there are no
           known regressions with CONFIG_NO_HZ_FULL=y enabled either.
      
         - the feature is not completely idempotent: there is no 100%
           equivalent replacement for a periodic scheduler/timer tick.  In
           particular there's ongoing work to map out and reduce its effects
           on scheduler load-balancing and statistics.  This should not impact
           correctness though, there are no known regressions related to this
           feature at this point.
      
         - it's a pretty ambitious feature that with time will likely be
           enabled by most Linux distros, and we'd like you to make input on
           its design/implementation, if you dislike some aspect we missed.
           Without flaming us to crisp! :-)
      
        Future plans:
      
         - there's ongoing work to reduce 1Hz to 0Hz, to essentially shut off
           the periodic tick altogether when there's a single busy task on a
           CPU.  We'd first like 1 Hz to be exposed more widely before we go
           for the 0 Hz target though.
      
         - once we reach 0 Hz we can remove the periodic tick assumption from
           nr_running>=2 as well, by essentially interrupting busy tasks only
           as frequently as the sched_latency constraints require us to do -
           once every 4-40 msecs, depending on nr_running.
      
        I am personally leaning towards biting the bullet and doing this in
        v3.10, like the -rt tree this effort has been going on for too long -
        but the final word is up to you as usual.
