  • Pull i2c new drivers from Wolfram Sang:
    "Here is a pull request from i2c hoping for the "new driver" rule.

    Originally, I wanted to send this request during the merge window, but
    code checkers with very recent additions complained, so a few fixups
    were needed. So, some more time went by and I merged rc1 to get a
    stable base"

    So the "new driver" rule is really about drivers that people absolutely
    need for the kernel to work on new hardware, which is not so much the
    case for i2c. So I considered not pulling this, but eventually
    relented.

    Just for FYI: the whole (and only) point of "new drivers" is not that
    new drivers cannot regress things (they can, and they have - by
    triggering badly tested code on machines that never triggered that code
    before), but because they can bring to life machines that otherwise
    wouldn't be useful at all without the drivers.

    So the new driver rule is for essential things that actual consumers
    would care about, ie devices like networking or disk drivers that matter
    to normal people (not server people - they run old kernels anyway, so
    mainlining new drivers is irrelevant for them).

  • Pull file locking fixes from Jeff Layton:
    "File locking related bugfixes

    Nothing too earth-shattering here. A fix for a potential regression
    due to a patch in pile #1, and the addition of a memory barrier to

  • Pull btrfs fixes from Chris Mason:
    "This fixes some lockups in btrfs reported with rc1. It probably has
    some performance impact because it is backing off our spinning locks
    more often and switching to a blocking lock. I'll be able to nail
    that down next week, but for now I want to get the lockups taken care
    of.

    Otherwise some more stack reduction and assorted fixes"

  • Pull ACPI and power management fixes from Rafael Wysocki:
    "These are fixes mostly (ia64 regression related to the ACPI
    enumeration of devices, cpufreq regressions, fix for I2C controllers
    included in Intel SoCs, mvebu cpuidle driver fix related to sysfs)
    plus additional kernel command line arguments from Kees to make it
    possible to build kernel images with hibernation and the kernel
    address space randomization included simultaneously, a new ACPI
    battery driver quirk for a system with a broken BIOS and a couple of
    ACPI core cleanups.

    Specifics:

    - Fix for an ia64 regression introduced during the 3.11 cycle by a
    commit that modified the hardware initialization ordering and made
    device discovery fail on some systems.

    - Fix for a build problem on systems where the cpufreq-cpu0 driver is
    built-in and the cpu-thermal driver is modular from Arnd Bergmann.

    - Fix for a recently introduced computational mistake in the
    intel_pstate driver that leads to excessive rounding errors from
    Doug Smythies.

    - Fix for a failure code path in cpufreq_update_policy() that fails
    to unlock the locks acquired previously from Aaron Plattner.

    - Fix for the cpuidle mvebu driver to use shorter state names which
    will prevent the sysfs interface from returning mangled strings.
    From Gregory Clement.

    - ACPI LPSS driver fix to make sure that the I2C controllers included
    in BayTrail SoCs are not held in the reset state while they are
    being probed from Mika Westerberg.

    - New kernel command line arguments making it possible to build
    kernel images with hibernation and kASLR included at the same time
    and to select which of them will be used via the command line (they
    are still functionally mutually exclusive, though). From Kees
    Cook.

    - ACPI battery driver quirk for Acer Aspire V5-573G that fails to
    send battery status change notifications timely from Alexander
    Mezin.

    - Two ACPI core cleanups from Christoph Jaeger and Fabian Frederick"

    - Fixes for races in the wait/wakeup logic used in blk-mq from
    Alexander. No issues have been observed, but it is definitely a
    bit flakey currently. Alternatively, we may drop the cyclic
    wakeups going forward, but that needs more testing.

    are used. From me.

    - A fix for a regression caused by the chunk size setting. It
    inadvertently used max_hw_sectors instead of max_sectors, which is
    incorrect, and causes hangs on btrfs multi-disk setups (where hw
    sectors apparently isn't set). From me.

    - Removal of WQ_POWER_EFFICIENT in the kblockd creation. This was a
    recent addition as well, but it actually breaks blk-mq which relies

  • If connector->dpms is left untouched, it defaults
    to DRM_MODE_DPMS_ON (0).

    As a result, drm_helper_connector_dpms will exit when
    it will be asked to set the state to DRM_MODE_DPMS_ON,
    because it is already set.

    That issue prevented displays from turning on at boot.

  • This config exists entirely to hide the cpufreq menu from the
    kernel configuration unless a platform has selected it. Nothing
    is actually built if this config is 'Y' and it just leads to more

    other CPUfreq option can be chosen. Let's remove the option so
    that we can always enable CPUfreq drivers on unicore32 platforms.

    architecture (also, blackfin and mips architectures define it). The
    related error (unicore32 with allmodconfig)

    In file included from drivers/scsi/mvsas/mv_94xx.c:27:

    And IRQ_SAS_A and IRQ_SAS_B are used as 'u32' (although "enum
    pci_interrupt_cause" is not used directly, now).

    All together, need add 'MVS_' for "enum pci_interrupt_cause".
