  • Pull sound updates from Takashi Iwai:
    "This contains pretty many small commits covering fairly large range of
    files in sound/ directory. Partly because of additional API support
    and partly because of constantly developed ASoC and ARM stuff.

    Some highlights:

    - Introduced the helper function and documentation for exposing the
    channel map via control API, as discussed in Plumbers; most of PCI
    drivers are covered, will follow more drivers later

    - Most of drivers have been replaced with the new PM callbacks (if
    the bus is supported)

    - HD-audio controller got the support of runtime PM and the support
    of D3 clock-stop. Also changing the power_save option in sysfs
    kicks off immediately to enable / disable the power-save mode.

    - Another significant code change in HD-audio is the rewrite of
    firmware loading code. Other than that, most of changes in
    HD-audio are continued cleanups and standardization for the generic
    auto parser and bug fixes (HBR, device-specific fixups), in
    addition to the support of channel-map API.

    - Addition of ASoC bindings for the compressed API, used by the
    mid-x86 drivers.

    - Lots of cleanups and API refreshes for ASoC codec drivers and
    DaVinci.

    - Conversion of OMAP to dmaengine.

    - New machine driver for Wolfson Microelectronics Bells.

    - New CODEC driver for Wolfson Microelectronics WM0010.

    - Enhancements to the ux500 and wm2000 drivers

    - A new driver for DA9055 and the support for regulator bypass mode."

    Fix up various arm soc header file reorg conflicts.

  • Change de_thread() to use KILLABLE rather than UNINTERRUPTIBLE while
    waiting for other threads. The only complication is that we should
    clear ->group_exit_task and ->notify_count before we return, and we
    should do this under tasklist_lock. -EAGAIN is used to match the
    initial signal_group_exit() check/return, it doesn't really matter.

    This fixes the (unlikely) race with coredump. de_thread() checks
    signal_group_exit() before it starts to kill the subthreads, but this
    can't help if another CLONE_VM (but non CLONE_THREAD) task starts the
    coredumping after de_thread() unlocks ->siglock. In this case the
    killed sub-thread can block in exit_mm() waiting for coredump_finish(),
    execing thread waits for that sub-thead, and the coredumping thread
    waits for execing thread. Deadlock.

  • Pull sparc changes from David S Miller:
    "There is an attempt to fix a bad interaction between syscall tracing
    and force_successful_syscall() from Al Viro, but it needs to be redone
    as it introduced regressions and thus had to be reverted for now.

    Al is working on an updated version.

    But what we do have here are some significant bzero/memset
    improvements for Niagara-4. An 8K page can be cleared in around 600
    cycles, because we essentially have a store that behaves like
    powerpc's dcbz that we can actually make real use of."

  • task_work_run() implementation had the side effect of enabling
    interrupts. With commit ac3d0da8 (task_work: Make task_work_add()
    lockless), interrupts are no longer enabled revealing the bug in the
    arch code. This patch enables the interrupt explicitly before calling
    do_notify_resume().

  • Following commit 74838b7 (swiotlb: add the late swiotlb initialization
    function with iotlb memory) the swiotlb_init_with_default_size() is a
    static function. This patch changes the arm64 code to call
    swiotlb_init() instead and use the default size of 64MB. It is assumed
    that AArch64 platforms have enough RAM to afford the pre-allocated
    swiotlb memory. It also removes the #ifdef around this call since
    CONFIG_SWIOTLB is always enabled.

  • Pull UBI fastmap changes from Artem Bityutskiy:
    "This pull request contains the UBI fastmap support implemented by
    Richard Weinberger from Linutronix. Fastmap is designed to address
    UBI's slow scanning issues. Namely, it introduces a new on-flash
    data-structure called "fastmap", which stores the information about
    logicalphysical eraseblocks mappings. So now to get this
    information just read the fastmap, instead of doing full scan. More
    information here can be found in Richard's announcement in LKML
    (Subject: UBI: Fastmap request for inclusion (v19)):

    http://thread.gmane.org/gmane.linux.kernel/1364922/focus=1369109

    One thing I want to explicitly say is that fastmap did not have large
    enough linux-next exposure. It is partially my fault - I did not
    respond quickly enough. I _really_ apologize for this. But it had
    good testing and disabled by default, so I do not expect that we'll
    break anything.

    Fastmap is declared as experimental so far, and it is off by default.
    We did declare that the on-flash format may be changed. The reason
    for this is that no one used it in real production so far, so there is
    a high risk that something is missing. Besides, we do not have
    user-space tools supporting fastmap so far.

    Nevertheless, I suggest we merge this feature. Many people want UBI's
    scanning bottleneck to be fixed and merging fastmap now should
    accelerate its production use. The plan is to make it bullet-prove,
    somewhat clean-up, and make it the default for UBI. I do not know how
    many kernel releases will it take.

    Basically, I what I want to do for fastmap is something like Linus did
    for btrfs few years ago."

    - New driver for "address decoder controller" for mvebu, which is a
    piece of hardware that configures addressable devices and
    peripherals. First user is the boot rom aperture on armada XP
    since it is needed for SMP support.
    - New device tree bindings for peripherals such as gpio-fan, iconnect
    nand, mv_cesa and the above address decoder controller.
    - Some defconfig updates, mostly to enable new DT boards and a few

  • Pull media updates from Mauro Carvalho Chehab:
    "The first part of the media updates for Kernel 3.7.

    This series contain:

    - A major tree renaming patch series: now, drivers are organized
    internally by their used bus, instead of by V4L2 and/or DVB API,
    providing a cleaner driver location for hybrid drivers that
    implement both APIs, and allowing to cleanup the Kconfig items and
    make them more intuitive for the end user;

    - Media Kernel developers are typically very lazy with their duties
    of keeping the MAINTAINERS entries for their drivers updated. As
    now the tree is more organized, we're doing an effort to add/update
    those entries for the drivers that aren't currently orphan;

    - Several DVB USB drivers got moved to a new DVB USB v2 core; the new
    core fixes several bugs (as the existing one that got bitroted).
    Now, suspend/resume finally started to work fine (at least with
    some devices - we should expect more work with regards to it);

    - added multistream support for DVB-T2, and unified the API for
    DVB-S2 and ISDB-S. Backward binary support is preserved;

    - as usual, a few new drivers, some V4L2 core improvements and lots
    of drivers improvements and fixes.

    There are some points to notice on this series:

    1) you should expect a trivial merge conflict on your tree, with the
    removal of Documentation/feature-removal-schedule.txt: this series
    would be adding two additional entries there. I opted to not
    rebase it due to this recent change;

    2) With regards to the PCTV 520e udev-related breakage, I opted to
    fix it in a way that the patches can be backported to 3.5 even
    without your firmware fix patch. This way, Greg doesn't need to
    rush backporting your patch (as there are still the firmware cache
    and firmware path customization issues to be addressed there).

    I'll send later a patch (likely after the end of the merge window)
    reverting the rest of the DRX-K async firmware request, fully
    restoring its original behaviour to allow media drivers to
    initialize everything serialized as before for 3.7 and upper.

    3) I'm planning to work on this weekend to test the DMABUF patches
    for V4L2. The patches are on my queue for several Kernel cycles,
    but, up to now, there is/was no way to test the series locally.

    I have some concerns about this particular changeset with regards
    to security issues, and with regards to the replacement of the old
    VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
    GPU drivers change. The Overlay API allows direct PCI2PCI
    transfers from a media capture card into the GPU framebuffer, but
    its API is crappy. Also, the only existing X11 driver that
    implements it requires a XV extension that is not available
    anymore on modern drivers. The DMABUF can do the same thing, but
    with it is promising to be a properly-designed API. If I can
    successfully test this series and be happy with it, I should be
    asking you to pull them next week."

  • Pull UAPI disintegration fixes from David Howells:
    "There are three main parts:

    (1) I found I needed some more fixups in the wake of testing Arm64
    (some asm/unistd.h files had weird guards that caused problems -
    mostly in arches for which I don't have a compiler) and some
    __KERNEL__ splitting needed to take place in Arm64.

    (2) I found that c6x was missing some __KERNEL__ guards in its
    asm/signal.h. Mark Salter pointed me at a tree with a patch to
    remove that file entirely and use the asm-generic variant instead.

    (3) Lastly, m68k turned out to have a header installation problem due
    to it lacking a kvm_para.h file.

    The conditional installation bits for linux/kvm_para.h, linux/kvm.h
    and linux/a.out.h weren't very well specified - and didn't work if
    an arch didn't have the asm/ version of that file, but there *was*
    an asm-generic/ version.

    It seems the "ifneq $((wildcard ...),)" for each of those three
    headers in include/kernel/Kbuild is invoked twice during header
    installation, and the second time it matches on the just installed
    asm-generic/kvm_para.h file and thus incorrectly installs
    linux/kvm_para.h as well.

    Most arches actually have an asm/kvm_para.h, so this wasn't
    detectable in those."

    on Xen on ARM (specifically ARMv7 with virtualized extensions). PV
    console, block and network frontend/backends are working.
    Bug-fixes:
    * Fix compile linux-next fallout.
    * Fix PVHVM bootup crashing.

    The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports
    ARMv7 platforms.

    The goal in implementing this architecture is to exploit the hardware
    as much as possible. That means use as little as possible of PV
    operations (so no PV MMU) - and use existing PV drivers for I/Os
    (network, block, console, etc). This is similar to how PVHVM guests
    operate in X86 platform nowadays - except that on ARM there is no need
    for QEMU. The end result is that we share a lot of the generic Xen
    drivers and infrastructure.

    Details on how to compile/boot/etc are available at this Wiki:

    and this blog has links to a technical discussion/presentations on the
    overall architecture:

  • Add support to export the device description obtained from the ACPI _STR
    method, if one exists for a device, to user-space via a sysfs interface.
    This new interface provides a standard and platform neutral way for users
    to obtain the description text stored in the ACPI _STR method. If no
    _STR method exists for the device, no sysfs 'description' file will be
    created. The 'description' file will be located in the /sys/devices/
    directory using the device's path.

    /sys/device///.../firmware_node/description

    Example:

    /sys/devices/pci0000:00/0000:00.07.0/0000:0e:00.0/firmware_node/description

    It can also be located using the ACPI device path, for example:

    /sys/devices/LNXSYSTM:00/device:00/ACPI0004:00/PNP0A08:00/device:13/device:15/description
    /sys/devices/LNXSYSTM:00/device:00/ACPI0004:00/ACPI0004:01/ACPI0007:02/description

    Execute the 'cat' command on the 'description' file to obtain the
    description string for that device.

    This patch also includes documentation describing how the new sysfs
    interface works

    Changes from v1-v2 based on comments by Len Brown and Fengguang Wu
    * Removed output "No Description" and leaving a NULL attribute if the
    _STR method failed to evaluate.

    * In acpi_device_remove_files() removed the redundent check of
    dev->pnp.str_obj before calling free. This check triggered a message
    from smatch.

  • Parsing acpi table entries may fall into an infinite loop on a buggy BIOS
    which has entry length=0 in acpi table.

    Instead of kernel hang with few failure clue which leads to heavy lifting debug
    effort, this patch hardens kernel boot by booting into non NUMA mode. The debug
    info left in log buffer helps people identify the issue.

  • Counting SMIs is popular, so add a dedicated "-s" option to do it,
    and juggle some of the other option letters.

    -S is now system summary (was -s)
    -c is 32 bit counter (was -d)
    -C is 64-bit counter (was -D)
    -p is 1st thread in core (was -c)
    -P is 1st thread in package (was -p)

    bump the minor version number
