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"

Pull tracing updates from Steven Rostedt:
 "As the merge window is still open, and this code was not as complex as
  I thought it might be.  I'm pushing this in now.

  This will allow Thomas to debug his irq work for 3.20.

  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.

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.

Prepare input updates for 3.19.

virtio wants to read bitwise types from userspace using get_user.  At the
moment this triggers sparse errors, since the value is passed through an
integer.

Fix that up using __force.

Xtensa improvements for 3.19:

- fix permissions for kmapped pages so that copy_to_user_page works with
  them;
- add power management menu to Kconfig to allow use of runtime PM.

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"

Pull drm updates from Dave Airlie:
 "Highlights:

   - 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

  Other stuff:

   - core:
        panel - MIPI DSI + new panels.
        expose suggested x/y properties for virtual GPUs

   - i915:

        gen3/4 reset work
        start of dri1/ums removal

        fixes for lots of things.

   - nouveau:
        tegra k1 voltage support
        GM204 modesetting support
        GT21x memory reclocking work

   - radeon:
        CI dpm fixes
        GPUVM improvements
        Initial DPM fan control

   - rcar-du:
