      KVM: ioapic: try to recover if pending_eoi goes out of range · 4009b249
      Paolo Bonzini authored
      The RTC tracking code tracks the cardinality of rtc_status.dest_map
      into rtc_status.pending_eoi.  It has some WARN_ONs that trigger if
      pending_eoi ever becomes negative; however, these do not do anything
      to recover, and it bad things will happen soon after they trigger.
      
      When the next RTC interrupt is triggered, rtc_check_coalesced() will
      return false, but ioapic_service will find pending_eoi != 0 and
      do a BUG_ON.  To avoid this, should pending_eoi ever be nonzero,
      call kvm_rtc_eoi_tracking_restore_all to recompute a correct
      dest_map and pending_eoi.

      KVM: ioapic: fix assignment of ioapic->rtc_status.pending_eoi (CVE-2014-0155) · 5678de3f
      Paolo Bonzini authored
      QE reported that they got the BUG_ON in ioapic_service to trigger.
      I cannot reproduce it, but there are two reasons why this could happen.
      
      The less likely but also easiest one, is when kvm_irq_delivery_to_apic
      does not deliver to any APIC and returns -1.
      
      Because irqe.shorthand == 0, the kvm_for_each_vcpu loop in that
      function is never reached.  However, you can target the similar loop in
      kvm_irq_delivery_to_apic_fast; just program a zero logical destination
      address into the IOAPIC, or an out-of-range physical destination address.

      Pull kvm updates from Paolo Bonzini:
       "PPC and ARM do not have much going on this time.  Most of the cool
        stuff, instead, is in s390 and (after a few releases) x86.
      
        ARM has some caching fixes and PPC has transactional memory support in
        guests.  MIPS has some fixes, with more probably coming in 3.16 as
        QEMU will soon get support for MIPS KVM.
      
        For x86 there are optimizations for debug registers, which trigger on
        some Windows games, and other important fixes for Windows guests.  We
        now expose to the guest Broadwell instruction set extensions and also
        Intel MPX.  There's also a fix/workaround for OS X guests, nested
        virtualization features (preemption timer), and a couple kvmclock
        refinements.
      
        For s390, the main news is asynchronous page faults, together with
        improvements to IRQs (floating irqs and adapter irqs) that speed up
        virtio devices"

      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.

      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,

      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
        this had the potential of information leaks"

      x86: Fix dumpstack_64 irq stack handling · 63c95654
      Steven Rostedt (Red Hat) authored
      Commit 2223f6f6 "x86: Clean up dumpstack_64.c code" changed
      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.

      x86: Fix dumpstack_64 to keep state of "used" variable in loop · 1aabc599
      Steven Rostedt (Red Hat) authored
      Commit 2223f6f6 "x86: Clean up dumpstack_64.c code" moved the used
      variable to a local within the loop, but the in_exception_stack()
      depended on being non-volatile with the ability to change it.
      
      By always re-initializing the "used" variable to zero, it would cause
      the in_exception_stack() to return the same thing each time, and
      cause the dump_stack loop to go into an infinite loop.

      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"

         - Support for configuration of the initial state for gpio regulators
           with multi-voltage support.
