      Pull ext4 updates from Ted Ts'o:
       "The big new feature added this time is supporting online resizing
        using the meta_bg feature.  This allows us to resize file systems
        which are greater than 16TB.  In addition, the speed of online
        resizing has been improved in general.
      
        We also fix a number of races, some of which could lead to deadlocks,
        in ext4's Asynchronous I/O and online defrag support, thanks to good
        work by Dmitry Monakhov.
      
        There are also a large number of more minor bug fixes and cleanups
        from a number of other ext4 contributors, quite of few of which have
        submitted fixes for the first time."

       "This is the first chunk of ARM updates for this merge window.

        mach-integrator/integrator_cp.c.  Nothing particularly stands out more
        than anything else.

      Pull late ARM soc platform updates from Olof Johansson:
       "This branch contains updates to OMAP and Marvell platforms (kirkwood,
        dove, mvebu) that came in after we had done the big multiplatform
        merges, so they were kept separate from the rest, and not separated
        into the traditional topics of cleanup/driver/platform features.
      
        For OMAP, the updates are:
         - Runtime PM conversions for the GPMC and RNG IP blocks
         - Preparation patches for the OMAP common clock framework conversion
         - clkdev alias additions required by other drivers
         - Performance Monitoring Unit (PMU) support for OMAP2, 3, and
           non-4430 OMAP4
         - OMAP hwmod code and data improvements
         - Preparation patches for the IOMMU runtime PM conversion
         - Preparation patches for OMAP4 full-chip retention support
      
        For Kirkwood/Dove/mvebu:
         - 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
           drivers.
         - New drivers using the pincontrol subsystem for dove, kirkwood and
           mvebu
         - New clean gpio driver for mvebu"

      Linus Torvalds authored
      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."

       (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

         * 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.

      Jean Delvare authored
      
      
      Now that i2c-mux-gpio is able to find the GPIO chip by itself, we can
      delegate this task. The great thing here is that i2c-mux-gpio can
      defer device probing until the gpio chip is available, so we no longer
      depend on the module loading order.

      i2c-mux-gpio: Add support for dynamically allocated GPIO pins · e7ee5140
      Jean Delvare authored
      
      
      The code instantiating an i2c-mux-gpio platform device doesn't
      necessarily know in advance the GPIO pin numbers it wants to use. If
      pins are on a GPIO device which gets its base GPIO number assigned
      dynamically at run-time, the values can't be hard-coded.
      
      In that case, let the caller tell i2c-mux-gpio the name of the GPIO
      chip and the (relative) GPIO pin numbers to use. At probe time, the
      i2c-mux-gpio driver will look for the chip and apply the proper offset
      to turn relative GPIO pin numbers to absolute GPIO pin numbers.
      
      The same could be (and was so far) done on the caller's end, however
      doing it in i2c-mux-gpio has two benefits:
      * It avoids duplicating the code on every caller's side (about 30
        lines of code.)
      * It allows for deferred probing for the muxed part of the I2C bus
        only. If finding the GPIO chip is the caller's responsibility, then
        deferred probing (if the GPIO chip isn't there yet) will not only
        affect the mux and the I2C bus segments behind it, but also the I2C
        bus trunk.

      i2c-i801: Support SMBus multiplexing on Asus Z8 series · 3ad7ea18
      Jean Delvare authored
      
      
      Add support for SMBus multiplexing on Asus Z8 motherboard series. On
      these boards, the memory slots are behind a GPIO-controlled I2C
      multiplexer. Models with 6 or 12 memory slots have 2 segments behind
      the multiplexer, while models with 18 memory slots have 3 such
      segments.
      
      On these boards, only the memory slots are behind the multiplexer,
      so it is possible to keep the autodetection mechanism.
      
      The code is generic enough so it could work on other boards as long as
      the multiplexer is controlled by GPIO pins. For other forms of
      multiplexing (for example using an I2C device) additional code will be
      needed.
      
      Thanks to Asus for providing a board to develop and test this feature,
      as well as all the technical information required.
      
      At the moment, the GPIO driver must be loaded before the i2c-i801
      driver, but I hope to solve this soon, using deferred probing on
      the i2c-mux-gpio side.

      i2c: Make I2C available on UML · 3ddb59d4
      Peter Huewe authored
      
      
      Remove the global dependency of the I2C subsystem on HAS_IOMEM and
      move the dependency to the i2c/busses submenu, with an exception for
      i2c-stub.
      
      The generic I2C part does not need to have HAS_IOMEM set and thus now
      becomes available in UML, so the I2C subsystem can now be used, e.g.
      by the i2c-stub driver, for development of I2C device drivers.

      Convert the struct i2c_msg initialization to C99 format. This makes
      maintaining and editing the code simpler. Also helps once other fields
      like transferred are added in future.

      i2c-smbus: Convert kzalloc to devm_kzalloc · 71b57845
      Julia Lawall authored
      Converting kzalloc to devm_kzalloc simplifies the code and ensures that the
      result, alert, is freed after the irq allocated by the subsequent
      devm_request_irq.  This in turn ensures that when an interrupt can be
      triggered, the alert structure is still available.
      
      The problem of a free after a devm_request_irq was found using the
      following semantic match (http://coccinelle.lip6.fr/
      
      )
      
      // <smpl>
      @r exists@
      expression e1,e2,x,a,b,c,d;
      identifier free;

        devm_request_irq@p1(e1,e2,...,x)

            when != e2 = a
            when != x = b
        if (...) {

              when != x = d

      i2c-mux: Add support for device auto-detection · eee543e8
      Jean Delvare authored
      
      
      Let I2C bus segments behind multiplexers have a class. This allows for
      device auto-detection on these segments. As long as parent segments
      don't share the same class, it should be fine.
      
      I implemented support in drivers i2c-mux-gpio and i2c-mux-pca954x. I
      left i2c-mux-pca9541 and i2c-mux-pinctrl alone for the moment as I
      don't know if this feature makes sense for the use cases of these
      drivers.

           paves the way for supporting different platform backends, along
           with some rework of the PCIe code for the PowerNV platform in order
           to remove home made resource allocations and instead use the
           generic code (which is possible after some small improvements to it
           done by Gavin).
      
         - Uprobes support by Ananth N Mavinakayanahalli
      
         - A pile of embedded updates from Freescale folks, including new SoC
           and board supports, more KVM stuff including preparing for 64-bit

      Fix the warning:
      
        WARNING: vmlinux.o(.text+0x14cfd8): Section mismatch in reference from the variable compressed_formats to the function .init.text:gunzip()
        The function compressed_formats() references
        the function __init gunzip().
        etc..
      
      Within decompress.c, compressed_formats[] needs 'a __initdata annotation',
      because some of it's data members refer to functions which will be
      unloaded after init.
      
      Consequently, its user decompress_method() will get the __init prefix.

      kernel/resource.c: fix stack overflow in __reserve_region_with_split() · 4965f566
      T Makphaibulchoke authored
      
      
      Using a recursive call add a non-conflicting region in
      __reserve_region_with_split() could result in a stack overflow in the case
      that the recursive calls are too deep.  Convert the recursive calls to an
      iterative loop to avoid the problem.
      
      Tested on a machine containing 135 regions.  The kernel no longer panicked
      with stack overflow.
      
      Also tested with code arbitrarily adding regions with no conflict,
      embedding two consecutive conflicts and embedding two non-consecutive
      conflicts.
