      hwrng: bcm2835 - fix oops when rng h/w is accessed during registration · eb4a5346
      Matt Porter 提交于
      Commit "d9e79726 hwrng: add randomness to system from rng sources"
      exposed a bug in the bcm2835-rng driver resulting in boot failure
      on Raspberry Pi due to the following oops:
      
      [   28.261523] BUG: soft lockup - CPU#0 stuck for 23s! [swapper:1]
      [   28.271058]
      [   28.275958] CPU: 0 PID: 1 Comm: swapper Not tainted 3.14.0+ #11
      [   28.285374] task: db480000 ti: db484000 task.ti: db484000
      [   28.294279] PC is at bcm2835_rng_read+0x28/0x48
      [   28.302276] LR is at hwrng_register+0x1a8/0x238
      .
      .
      .
      
      The RNG h/w is not completely initialized and enabled before
      hwrng_register() is called and so the bcm2835_rng_read() fails.
      Fix this by making the warmup/enable writes before registering
      the RNG source with the hwrng core.

      pidns_get()->get_pid_ns() can hit ns == NULL. This task_struct can't
      go away, but task_active_pid_ns(task) is NULL if release_task(task)
      was already called. Alternatively we could change get_pid_ns(ns) to
      check ns != NULL, but it seems that other callers are fine.

        now expose to the guest Broadwell instruction set extensions and also

      Linus Torvalds 提交于
      Pull more ACPI and power management updates from Rafael Wysocki:
       "These are commits that were not quite ready when I sent the original
        pull request for 3.15-rc1 several days ago, but they have spent some
        time in linux-next since then and appear to be good to go.  All of
        them are fixes and cleanups.
      
        Specifics:
      
         - Remaining changes from upstream ACPICA release 20140214 that
           introduce code to automatically serialize the execution of methods
           creating any named objects which really cannot be executed in
           parallel with each other anyway (previously ACPICA attempted to
           address that by aborting methods upon conflict detection, but that
           wasn't reliable enough and led to other issues).  From Bob Moore
           and Lv Zheng.
      
         - intel_pstate fix to use del_timer_sync() instead of del_timer() in
           the exit path before freeing the timer structure from Dirk
           Brandewie (original patch from Thomas Gleixner).
      
         - cpufreq fix related to system resume from Viresh Kumar.
      
         - Serialization of frequency transitions in cpufreq that involve
           PRECHANGE and POSTCHANGE notifications to avoid ordering issues
           resulting from race conditions.  From Srivatsa S Bhat and Viresh
           Kumar.
      
         - Revert of an ACPI processor driver change that was based on a
           specific interpretation of the ACPI spec which may not be correct
           (the relevant part of the spec appears to be incomplete).  From
           Hanjun Guo.
      
         - Runtime PM core cleanups and documentation updates from Geert
           Uytterhoeven.
      
         - PNP core cleanup from Michael Opdenacker"

        cost of losing the timers while asleep, and thus exploits the new
        timer broadcast framework to work around that limitation.

      Linus Torvalds 提交于
      Pull main powerpc updates from Ben Herrenschmidt:
       "This time around, the powerpc merges are going to be a little bit more
        complicated than usual.
      
        This is the main pull request with most of the work for this merge
        window.  I will describe it a bit more further down.
      
        There is some additional cpuidle driver work, however I haven't
        included it in this tree as it depends on some work in tip/timer-core
        which Thomas accidentally forgot to put in a topic branch.  Since I
        didn't want to carry all of that tip timer stuff in powerpc -next, I
        setup a separate branch on top of Thomas tree with just that cpuidle
        driver in it, and Stephen has been carrying that in next separately
        for a while now.  I'll send a separate pull request for it.
      
        Additionally, two new pieces in this tree add users for a sysfs API
        that Tejun and Greg have been deprecating in drivers-core-next.
        Thankfully Greg reverted the patch that removes the old API so this
        merge can happen cleanly, but once merged, I will send a patch
        adjusting our new code to the new API so that Greg can send you the
        removal patch.
      
        Now as for the content of this branch, we have a lot of perf work for
        power8 new counters including support for our new "nest" counters
        (also called 24x7) under pHyp (not natively yet).
      
        We have new functionality when running under the OPAL firmware
        (non-virtualized or KVM host), such as access to the firmware error
        logs and service processor dumps, system parameters and sensors, along
        with a hwmon driver for the latter.
      
        There's also a bunch of bug fixes accross the board, some LE fixes,
        and a nice set of selftests for validating our various types of copy
        loops.
      
        On the Freescale side, we see mostly new chip/board revisions, some
        clock updates, better support for machine checks and debug exceptions,
        etc..."

      Linus Torvalds 提交于
      Pull x86 vdso changes from Peter Anvin:
       "This is the revamp of the 32-bit vdso and the associated cleanups.
      
        This adds timekeeping support to the 32-bit vdso that we already have
        in the 64-bit vdso.  Although 32-bit x86 is legacy, it is likely to
        remain in the embedded space for a very long time to come.
      
        This removes the traditional COMPAT_VDSO support; the configuration
        variable is reused for simply removing the 32-bit vdso, which will
        produce correct results but obviously suffer a performance penalty.
        Only one beta version of glibc was affected, but that version was
        unfortunately included in one OpenSUSE release.
      
        This is not the end of the vdso cleanups.  Stefani and Andy have
        agreed to continue work for the next kernel cycle; in fact Andy has
        already produced another set of cleanups that came too late for this
        cycle.
      
        An incidental, but arguably important, change is that this ensures
        that unused space in the VVAR page is properly zeroed.  It wasn't
        before, and would contain whatever garbage was left in memory by BIOS
        or the bootloader.  Since the VVAR page is accessible to user space

      the irq_stack processing a little from what it was before.
      The irq_stack_end variable needed to be cleared after its first
      use. By setting irq_stack to the per cpu irq_stack and passing
      that to analyze_stack(), and then clearing it after it is processed,
      we can get back the original behavior.

      Linus Torvalds 提交于
      Pull sound updates from Takashi Iwai:
       "There have been lots of changes in ALSA core, HD-audio and ASoC, also
        most of PCI drivers touched by conversions of printks.  All these
        resulted in a high volume and wide ranged patch sets in this release.
        Many changes are fairly trivial, but also lots of nice cleanups and
        refactors.  There are a few new drivers, most notably, the Intel
        Haswell and Baytrail ASoC driver.
      
        Core changes:
         - A bit modernization; embed the device struct into snd_card struct,
           so that it may be referred from the beginning.  A new
           snd_card_new() function is introduced for that, and all drivers
           have been converted.
      
         - Simplification in the device management code in ALSA core; now
           managed by a simple priority list instead
      
         - Converted many kernel messages to use the standard dev_err() & co;
           this would be the pretty visible difference, especially for
           HD-audio.
      
        HD-audio:
         - Conexant codecs use the auto-parser as default now; the old static
           code still remains in case of regressions.  Some old quirks have
           been rewritten with the fixups for auto-parser.
      
         - C-Media codecs also use the auto-parser as default now, too.
      
         - A device struct is assigned to each HD-audio codec, and the
           formerly hwdep attributes are accessible over the codec sysfs, too.
           hwdep attributes still remain for compatibility.
      
         - Split the PCI-specific stuff for HD-audio controller into a
           separate module, ane make a helper module for the generic
           controller driver.  This is a preliminary change for supporting
           Tegra HDMI controller in near future, which slipped from 3.15
           merge.
      
         - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
           fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
           laptop headset quirks
      
         - Make the HD-audio codec response a bit more robust
      
         - A few improvements on Realtek ALC282 / 283 about the pop noises
      
         - A couple of Intel HDMI fixes
      
        ASoC:
         - Lots of cleanups for enumerations; refactored lots of error prone
           original codes to use more modern APIs
      
         - Elimination of the ASoC level wrappers for I2C and SPI moving us
           closer to converting to regmap completely and avoiding some
           randconfig hassle
      
         - Provide both manually and transparently locked DAPM APIs rather
           than a mix of the two fixing some concurrency issues
      
         - Start converting CODEC drivers to use separate bus interface
           drivers rather than having them all in one file helping avoid
           dependency issues
      
         - DPCM support for Intel Haswell and Bay Trail platforms, lots of
           fixes
      
         - Lots of work on improvements for simple-card, DaVinci and the
           Renesas rcar drivers.
      
         - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
           the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
      
         - Fixes for the simple-card DAI format DT mess
      
         - DT support for a couple more devices.
      
         - Use of the tdm_slot mapping in a few drivers
      
        Others:
         - Support of reset_resume callback for improved S4 in USB-audio
           driver; the device with boot quirks have been little tested, which
           we need to watch out in this development cycle
      
         - Add PM support for ICE1712 driver (finally!); it's still pretty
           partial support, only for M-Audio devices"

      netpoll: Use skb_irq_freeable to make zap_completion_queue safe. · b1586f09
      Eric W. Biederman 提交于
      Replace the test in zap_completion_queue to test when it is safe to
      free skbs in hard irq context with skb_irq_freeable ensuring we only
      free skbs when it is safe, and removing the possibility of subtle
      problems.

      net: Add a test to see if a skb is freeable in irq context · 574f7194
      Eric W. Biederman 提交于
      Currently netpoll and skb_release_head_state assume that a skb is
      freeable in hard irq context except when skb->destructor is set.
      
      The reality is far from this.  So add a function skb_irq_freeable to
      compute the full test and in the process be the living documentation
      of what the requirements are of actually freeing a skb in hard irq
      context.

      ====================
      this is a pull request of 16 patches for the 3.15 release cycle.
      
      Bjorn Van Tilt contributes a patch which fixes a memory leak in usb_8dev's
      usb_8dev_start_xmit()s error path. A patch by Robert Schwebel fixes a typo in
      the can documentation. The remaining patches all target the c_can driver. Two
      of them are by me; they add a missing netif_napi_del() and return value
      checking. Thomas Gleixner contributes 12 patches, which address several
      shortcomings in the driver like hardware initialisation, concurrency, message
      ordering and poor performance.

      qlcnic: Fix build failure due to undefined reference to `vxlan_get_rx_port' · 7f1f6056
      Shahed Shaikh 提交于
      Commit 2b3d7b75("qlcnic: Add VXLAN Rx offload support") uses
      vxlan_get_rx_port() which caused build failure when VXLAN=m.
      
      This patch fixes the build failure by adding dependency on VXLAN
      in Kconfig of qlcnic module and use vxlan_get_rx_port() and support
      code accordingly.
