  • Pull first round of SCSI updates from James Bottomley:
    "This patch consists of the usual driver updates (megaraid_sas,
    scsi_debug, qla2xxx, qla4xxx, lpfc, bnx2fc, be2iscsi, hpsa, ipr) plus
    an assortment of minor fixes and the first precursors of SCSI-MQ (the
    code path simplifications) and the bug fix for the USB oops on remove
    (which involves an infrastructure change, so is sent via the main tree
    with a delayed backport after a cycle in which it is shown to
    introduce no new bugs)"

  • 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"

  • 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.

    Specifics:

    - 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.

    - ACPI fan and thermal optimizations related to system suspend and
    resume from Aaron Lu.

    - cpuidle fixes related to the menu governor from Tuukka Tikkanen.

    - cpuidle fix related to coupled CPUs handling from Paul Burton.

    - Asynchronous execution of all device suspend and resume callbacks,
    except for ->prepare and ->complete, during system suspend and
    resume from Chuansheng Liu.

    - Delayed resuming of runtime-suspended devices during system suspend
    for the PCI bus type and ACPI PM domain.

    - New set of PM helper routines to allow device runtime PM callbacks
    to be used during system suspend and resume more easily from Ulf
    Hansson.

    "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
    code.

    - 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"

    "A lot of activities on libata side this time.

    - A lot of changes around ahci. Various embedded platforms are
    implementing ahci controllers. Some were built atop ahci_platform,
    others were doing their own things. Hans made some structural
    changes to libahci and librarized ahci_platform so that ahci
    platform drivers can share more common code. A couple platform
    drivers are added on top of that and several are added to replace
    older drivers which were doing their own things (older ones are
    scheduled to be removed).

    - Dan finishes the patchset to make libata PM operations
    asynchronous. Combined with one patch being routed through scsi,
    this should speed resume measurably.

    - Various fixes and cleanups from Bartlomiej and others"

    The interface has never been popular. This pull request contains
    patches to remove existing usages and kill the interface. As one of

  • 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
    defines __ARCH_WANT_COMPAT_SYS_PREADV64/PWRITEV64.

    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"

  • Commit 03bbcb2e7e2 (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.
