      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.

      Linus Torvalds authored
      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
         - 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
         - 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
         - 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
         - 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
         - 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

      Pull ACPI and power management updates from Rafael Wysocki:
       "The majority of this material spent some time in linux-next, some of
        it even several weeks.  There are a few relatively fresh commits in
        it, but they are mostly fixes and simple cleanups.
        ACPI took the lead this time, both in terms of the number of commits
        and the number of modified lines of code, cpufreq follows and there
        are a few changes in the PM core and in cpuidle too.
        A new feature that already got some LWN.net's attention is the device
        PM QoS extension allowing latency tolerance requirements to be
        propagated from leaf devices to their ancestors with hardware
        interfaces for specifying latency tolerance.  That should help systems
        with hardware-driven power management to avoid going too far with it
        in cases when there are latency tolerance constraints.
        There also are some significant changes in the ACPI core related to
        the way in which hotplug notifications are handled.  They affect PCI
        hotplug (ACPIPHP) and the ACPI dock station code too.  The bottom line
        is that all those notification now go through the root notify handler
        and are propagated to the interested subsystems by means of callbacks
        instead of having to install a notify handler for each device object
        that we can potentially get hotplug notifications for.
        In addition to that ACPICA will now advertise "Windows 2013"
        compatibility for _OSI, because some systems out there don't work
        correctly if that is not done (some of them don't even boot).
        On the system suspend side of things, all of the device suspend and
        resume callbacks, except for ->prepare() and ->complete(), are now
        going to be executed asynchronously as that turns out to speed up
        system suspend and resume on some platforms quite significantly and we
        have a few more optimizations in that area.
        Apart from that, there are some new device IDs and fixes and cleanups
        all over.  In particular, the system suspend and resume handling by
        cpufreq should be improved and the cpuidle menu governor should be a
        bit more robust now.
         - Device PM QoS support for latency tolerance constraints on systems
           with hardware interfaces allowing such constraints to be specified.
           That is necessary to prevent hardware-driven power management from
           becoming overly aggressive on some systems and to prevent power
           management features leading to excessive latencies from being used
           in some cases.
         - Consolidation of the handling of ACPI hotplug notifications for
           device objects.  This causes all device hotplug notifications to go
           through the root notify handler (that was executed for all of them
           anyway before) that propagates them to individual subsystems, if
           necessary, by executing callbacks provided by those subsystems
           (those callbacks are associated with struct acpi_device objects
           during device enumeration).  As a result, the code in question
           becomes both smaller in size and more straightforward and all of
           those changes should not affect users.
         - ACPICA update, including fixes related to the handling of _PRT in
           cases when it is broken and the addition of "Windows 2013" to the
           list of supported "features" for _OSI (which is necessary to
           support systems that work incorrectly or don't even boot without
           it).  Changes from Bob Moore and Lv Zheng.
         - Consolidation of ACPI _OST handling from Jiang Liu.
         - ACPI battery and AC fixes allowing unusual system configurations to
           be handled by that code from Alexander Mezin.
         - New device IDs for the ACPI LPSS driver from Chiau Ee Chew.

           resume from Chuansheng Liu.

      Pull irq code updates from Thomas Gleixner:
       "The irq department proudly presents:
         - Another tree wide sweep of irq infrastructure abuse.  Clear winner
           of the trainwreck engineering contest was:
               #include "../../../kernel/irq/settings.h"
         - Tree wide update of irq_set_affinity() callbacks which miss a cpu
           online check when picking a single cpu out of the affinity mask.
         - Tree wide consolidation of interrupt statistics.
         - Updates to the threaded interrupt infrastructure to allow explicit
           wakeup of the interrupt thread and a variant of synchronize_irq()
           which synchronizes only the hard interrupt handler.  Both are
           needed to replace the homebrewn thread handling in the mmc/sdhci
         - New irq chip callbacks to allow proper support for GPIO based irqs.
           The GPIO based interrupts need to request/release GPIO resources
           from request/free_irq.
         - A few new ARM interrupt chips.  No revolutionary new hardware, just
           differently wreckaged variations of the scheme.
         - Small improvments, cleanups and updates all over the place"

        The existing allocator linearly scanned the allocation map on both
        alloc and free without making use of hint or anything.  Al
        reimplemented the range allocator so that it can use binary search
        instead of linear scan during free and alloc path uses simple hinting
        to avoid scanning in common cases.  Combined, the new allocator
        resolves the scalability issue percpu allocator was showing during

      Pull s390 compat wrapper rework from Heiko Carstens:
       "S390 compat system call wrapper simplification work.
        The intention of this work is to get rid of all hand written assembly
        compat system call wrappers on s390, which perform proper sign or zero
        extension, or pointer conversion of compat system call parameters.
        Instead all of this should be done with C code eg by using Al's
        COMPAT_SYSCALL_DEFINEx() macro.
        Therefore all common code and s390 specific compat system calls have
        been converted to the COMPAT_SYSCALL_DEFINEx() macro.
        In order to generate correct code all compat system calls may only
        have eg compat_ulong_t parameters, but no unsigned long parameters.
        Those patches which change parameter types from unsigned long to
        compat_ulong_t parameters are separate in this series, but shouldn't
        cause any harm.
        The only compat system calls which intentionally have 64 bit
        parameters (preadv64 and pwritev64) in support of the x86/32 ABI
        haven't been changed, but are now only available if an architecture
        System calls which do not have a compat variant but still need proper
        zero extension on s390, like eg "long sys_brk(unsigned long brk)" will
        get a proper wrapper function with the new s390 specific
        COMPAT_SYSCALL_WRAPx() macro:
           COMPAT_SYSCALL_WRAP1(brk, unsigned long, brk);
        which generates the following code (simplified):
           asmlinkage long sys_brk(unsigned long brk);
           asmlinkage long compat_sys_brk(long brk)
               return sys_brk((u32)brk);
        Given that the C file which contains all the COMPAT_SYSCALL_WRAP lines
        includes both linux/syscall.h and linux/compat.h, it will generate
        build errors, if the declaration of sys_brk() doesn't match, or if
        there exists a non-matching compat_sys_brk() declaration.
        In addition this will intentionally result in a link error if
        somewhere else a compat_sys_brk() function exists, which probably
        should have been used instead.  Two more BUILD_BUG_ONs make sure the
        size and type of each compat syscall parameter can be handled
        correctly with the s390 specific macros.
        I converted the compat system calls step by step to verify the
        generated code is correct and matches the previous code.  In fact it
        did not always match, however that was always a bug in the hand
        written asm code.
        In result we get less code, less bugs, and much more sanity checking"

      x86: Adjust irq remapping quirk for older revisions of 5500/5520 chipsets · 6f8a1b33
      Neil Horman authored
      Commit 03bbcb2e
       (iommu/vt-d: add quirk for broken interrupt
      remapping on 55XX chipsets) properly disables irq remapping on the
      5500/5520 chipsets that don't correctly perform that feature.
      However, when I wrote it, I followed the errata sheet linked in that
      commit too closely, and explicitly tied the activation of the quirk to
      revision 0x13 of the chip, under the assumption that earlier revisions
      were not in the field.  Recently a system was reported to be suffering
      from this remap bug and the quirk hadn't triggered, because the
      revision id register read at a lower value that 0x13, so the quirk
      test failed improperly.  Given this, it seems only prudent to adjust
      this quirk so that any revision less than 0x13 has the quirk asserted.
      [ tglx: Removed the 0x12 comparison of pci id 3405 as this is covered
          	by the <= 0x13 check already ]
