  • When running in non-cache coherent configuration the memory that was
    allocated with dma_alloc_coherent() has a custom mapping and so there is no
    1-to-1 relationship between the kernel virtual address and the PFN. This
    means that virt_to_pfn() will not work correctly for those addresses and the
    default mmap implementation in the form of dma_common_mmap() will map some
    random, but not the requested, memory area.

    Fix this by providing a custom mmap implementation that looks up the PFN
    from the page table rather than using virt_to_pfn.

  • Pull ARM SoC/iommu configuration update from Arnd Bergmann:
    "The iomm-config branch contains work from Will Deacon, quoting his
    description:

    This series adds automatic IOMMU and DMA-mapping configuration for
    OF-based DMA masters described using the generic IOMMU devicetree
    bindings. Although there is plenty of future work around splitting up
    iommu_ops, adding default IOMMU domains and sorting out automatic IOMMU
    group creation for the platform_bus, this is already useful enough for
    people to port over their IOMMU drivers and start using the new probing
    infrastructure (indeed, Marek has patches queued for the Exynos IOMMU).

    The branch touches core ARM and IOMMU driver files, and the respective
    maintainers (Russell King and Joerg Roedel) agreed to have the
    contents merged through the arm-soc tree.

    The final version was ready just before the merge window, so we ended
    up delaying it a bit longer than the rest, but we don't expect to see
    regressions because this is just additional infrastructure that will
    get used in drivers starting in 3.20 but is unused so far"

    This adds two new features:

    1) Allow traceopoints to be enabled right after mm_init().

    By passing in the trace_event= kernel command line parameter,
    tracepoints can be enabled at boot up. For debugging things like
    the initialization of interrupts, it is needed to have tracepoints
    enabled very early. People have asked about this before and this
    has been on my todo list. As it can be helpful for Thomas to debug
    his upcoming 3.20 IRQ work, I'm pushing this now. This way he can
    add tracepoints into the IRQ set up and have users enable them when
    things go wrong.

    2) Have the tracepoints printed via printk() (the console) when they
    are triggered.

    If the irq code locks up or reboots the box, having the tracepoint
    output go into the kernel ring buffer is useless for debugging.
    But being able to add the tp_printk kernel command line option
    along with the trace_event= option will have these tracepoints
    printed as they occur, and that can be really useful for debugging
    early lock up or reboot problems.

    This code is not that intrusive and it passed all my tests. Thomas
    tried them out too and it works for his needs.

    Unfortunately enabling RCAR_AUDMAC_PP support this patch breaks dmaengine
    support on R-Car Gen2 boards. This should be resolved by driver updates
    in v3.20. But v3.19 was too early for this defconfig change.

  • The Exynos IOMMU driver uses the ARM specific dmac_flush_range() and
    outer_flush_range() functions. This breaks the build on arm64 allmodconfig
    in -next since support has been merged for some Exynos ARMv8 SoCs. Add a
    dependency on ARM to keep things building until either the driver has the
    ARM dependencies removed or the ARMv8 architecture code implements these
    ARM specific APIs.

  • The default linker behavior is to optimize identical literal values
    and remove unnecessary overhead. However, because of a bug in the
    linker, this currently results in an error ('call target out of range').

    Disable link-time optimizations per default until there is a fix
    for the linker and add the option to iss_defconfig.

  • Pull staging driver updates from Greg KH:
    "Here's the big staging tree pull request for 3.19-rc1.

    We continued to delete more lines than were added, always a good
    thing, but not at a huge rate this release, only about 70k lines
    removed overall mostly from removing the horrid bcm driver.

    Lots of normal staging driver cleanups and fixes all over the place,
    well over a thousand of them, the shortlog shows all the horrid
    details.

    The "contentious" thing here is the movement of the Android binder
    code out of staging into the "real" part of the kernel. This is code
    that has been stable for a few years now and is working as-is in the
    tens of millions of devices with no issues. Yes, the code is horrid,
    and the userspace api leaves a lot to be desired, but it's not going
    to change due to legacy issues that we have no control over. Because
    so many devices and companies rely on this, and the code is stable,
    might as well promote it out of staging.

    This was all discussed at the Linux Plumbers conference, and everyone
    participating agreed that this was the best way forward.

    There is work happening to replace the binder code with something new
    that is happening right now, but I don't expect to see the results of
    that work for another year at the earliest. If that ever happens, and
    Android switches over to it, I'll gladly remove this version.

    As for maintainers, I'll be glad to maintain this code, I've been
    doing it for the past few years with no problems. I'll send a
    MAINTAINERS entry for it before 3.19-final is out, still need to talk
    to the Google developers about if they are willing to help with it or
    not, last I checked they were, which was good.

    All of these patches have been in linux-next for a while with no
    reported issues"

    - AMD KFD driver merge

    This is the AMD HSA interface for exposing a lowlevel interface for
    GPGPU use. They have an open source userspace built on top of this
    interface, and the code looks as good as it was going to get out of
    tree.

    - Initial atomic modesetting work

    The need for an atomic modesetting interface to allow userspace to
    try and send a complete set of modesetting state to the driver has
    arisen, and been suffering from neglect this past year. No more,
    the start of the common code and changes for msm driver to use it
    are in this tree. Ongoing work to get the userspace ioctl finished
    and the code clean will probably wait until next kernel.

    - DisplayID 1.3 and tiled monitor exposed to userspace.

    Tiled monitor property is now exposed for userspace to make use of.

    - Rockchip drm driver merged.

    - imx gpu driver moved out of staging

  • The VM_FAULT_RETRY handling was confusing and incorrect for the case of
    returning to kernel mode. We need to handle the exception table fixup
    if we return to kernel mode due to a fatal signal - it will basically
    look to the kernel user mode access like the access failed due to the VM
    going away from udner it. Which is correct - the process is dying - and
    avoids the whole "repeat endless kernel page faults" case.

    Handling the VM_FAULT_RETRY early and in just one place also simplifies
    the mmap_sem handling, since once we've taken care of VM_FAULT_RETRY we
    know that we can just drop the lock. The remaining accounting and
    possible error handling is thread-local and does not need the mmap_sem.
