Pull powerpc updates from Ben Herrenschmidt:
 "This is the powerpc new goodies for 3.17.  The short story:

  The biggest bit is Michael removing all of pre-POWER4 processor
  support from the 64-bit kernel.  POWER3 and rs64.  This gets rid of a
  ton of old cruft that has been bitrotting in a long while.  It was
  broken for quite a few versions already and nobody noticed.  Nobody
  uses those machines anymore.  While at it, he cleaned up a bunch of
  old dusty cabinets, getting rid of a skeletton or two.

  Then, we have some base VFIO support for KVM, which allows assigning
  of PCI devices to KVM guests, support for large 64-bit BARs on
  "powernv" platforms, support for HMI (Hardware Management Interrupts)
  on those same platforms, some sparse-vmemmap improvements (for memory
  hotplug),

  There is the usual batch of Freescale embedded updates (summary in the
  merge commit) and fixes here or there, I think that's it for the
  highlights"

c5aec4c76a Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Ben Herrenschmidt:
 "Here is the bulk of the powerpc changes for this merge window.  It got
  a bit delayed in part because I wasn't paying attention, and in part
  because I discovered I had a core PCI change without a PCI maintainer
  ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
  probably improve it later and I didn't want to rebase to add his ack.

  There is going to be a bit more next week, essentially fixes that I
  still want to sort through and test.

  The biggest item this time is the support to build the ppc64 LE kernel
  with our new v2 ABI.  We previously supported v2 userspace but the
  kernel itself was a tougher nut to crack.  This is now sorted mostly
  thanks to Anton and Rusty.

  We also have a fairly big series from Cedric that add support for
  64-bit LE zImage boot wrapper.  This was made harder by the fact that
  traditionally our zImage wrapper was always 32-bit, but our new LE
  toolchains don't really support 32-bit anymore (it's somewhat there
  but not really "supported") so we didn't want to rely on it.  This
  meant more churn that just endian fixes.

  This brings some more LE bits as well, such as the ability to run in
  LE mode without a hypervisor (ie. under OPAL firmware) by doing the
  right OPAL call to reinitialize the CPU to take HV interrupts in the
  right mode and the usual pile of endian fixes.

  There's another series from Gavin adding EEH improvements (one day we
  *will* have a release with less than 20 EEH patches, I promise!).

  Another highlight is the support for the "Split core" functionality on
  P8 by Michael.  This allows a P8 core to be split into "sub cores" of
  4 threads which allows the subcores to run different guests under KVM
  (the HW still doesn't support a partition per thread).

  And then the usual misc bits and fixes ..."

- last but not least, the mandatory serial port

The patch also adds a defconfig file for this reference design that is
necessary because of the lowmem option that must be set higher due to
the number of PCIe devices with big ioremapped mem ranges on the boad.

e2c37d9083 powerpc: Added PCI MSI support using the HSTA module
The PPC476GTR SoC supports message signalled interrupts (MSI) by writing
to special addresses within the High Speed Transfer Assist (HSTA) module.

This patch adds support for PCI MSI with a new system device. The DMA
window is also updated to allow access to the entire 42-bit address range
to allow PCI devices write access to the HSTA module.

1b17366d69 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Ben Herrenschmidt:
 "So here's my next branch for powerpc.  A bit late as I was on vacation
  last week.  It's mostly the same stuff that was in next already, I
  just added two patches today which are the wiring up of lockref for
  powerpc, which for some reason fell through the cracks last time and
  is trivial.

  The highlights are, in addition to a bunch of bug fixes:

   - Reworked Machine Check handling on kernels running without a
     hypervisor (or acting as a hypervisor).  Provides hooks to handle
     some errors in real mode such as TLB errors, handle SLB errors,
     etc...

   - Support for retrieving memory error information from the service
     processor on IBM servers running without a hypervisor and routing
     them to the memory poison infrastructure.

   - _PAGE_NUMA support on server processors

   - 32-bit BookE relocatable kernel support

   - FSL e6500 hardware tablewalk support

   - A bunch of new/revived board support

   - FSL e6500 deeper idle states and altivec powerdown support

  You'll notice a generic mm change here, it has been acked by the
  relevant authorities and is a pre-req for our _PAGE_NUMA support"

device_type is a deprecated property, but some MDIO bus nodes still have
it. Except for a couple of old binding (compatible="gianfar" and

40aad3c1a9 dt/bindings: Remove all references to device_type "ethernet-phy"
The device_type property is deprecated for the flattened device tree and
the value "ethernet-phy" has never been defined as having a useful
meaning. Neither the kernel nor u-boot depend on it. It should never
have appeared in PHY bindings. This patch removes all references to
"ethernet-phy" as a device_type value from the documentation and the
.dts files.

This patch was generated mechanically with the following command and
then verified by looking at the diff.

Add elo3-dma-2.dtsi to support the third DMA controller.
This is used on T2080, T4240, B4860, etc.

FSL MPIC v4.3 adds a new discontiguous address range for internal interrupts,
e.g. internal interrupt 0 is at offset 0x200 and thus interrupt number is:
0x200 >> 5 = 16 in the device tree.  DMA controller 3 channel 0 internal
interrupt 240 is at offset 0x3a00, and thus the corresponding interrupt
number is: 0x3a00 >> 5 = 464, it's similar for other 7 interrupt numbers
of DMA 3 channels.

be2019816e powerpc/embedded6xx: Add support for Motorola/Emerson MVME5100
Add support for the Motorola/Emerson MVME5100 Single Board Computer.

The MVME5100 is a 6U form factor VME64 computer with:

	- A single MPC7410 or MPC750 CPU
	- A HAWK Processor Host Bridge (CPU to PCI) and
	  MultiProcessor Interrupt Controller (MPIC)
	- Up to 500Mb of onboard memory
	- A M48T37 Real Time Clock (RTC) and Non-Volatile Memory chip
	- Two 16550 compatible UARTS
	- Two Intel E100 Fast Ethernets
	- Two PCI Mezzanine Card (PMC) Slots
	- PPCBug Firmware

The HAWK PHB/MPIC is compatible with the MPC10x devices.

There is no onboard disk support. This is usually provided by installing a PMC
in first PMC slot.

This patch revives the board support, it was present in early 2.6
series kernels. The board support in those days was by Matt Porter of
MontaVista Software.

CSC Australia has around 31 of these boards in service. The kernel in use
for the boards is based on 2.6.31. The boards are operated without disks
from a file server.

This patch is based on linux-3.13-rc2 and has been boot tested.

Only boards with 512 Mb of memory are known to work.

16baeb307b powerpc/4xx: Fix warning in kilauea.dtb
Currently I see:
  DTC     arch/powerpc/boot/kilauea.dtb
Warning (reg_format): "reg" property in /plb/ppc4xx-msi@C10000000 has invalid length (12 bytes) (#address-cells == 1, #size-cells == 1)

It appears that unlike the other platforms handled by 3fb7933850
"powerpc/4xx: Adding PCIe MSI support" this platform does not use address-cells=2.

53567cf3c2 powerpc/85xx: typo in dts: "interupt" (four devices)
These lines were inoperative for four years, which puts some doubt into
their importance, and it's possible the fixed version will regress, but
at the very least they should be removed instead.

Linus Torvalds
e6d69a60b7 Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dmaengine changes from Vinod Koul:
 "This brings for slave dmaengine:

   - Change dma notification flag to DMA_COMPLETE from DMA_SUCCESS as
     dmaengine can only transfer and not verify validaty of dma
     transfers

   - Bunch of fixes across drivers:

      - cppi41 driver fixes from Daniel

      - 8 channel freescale dma engine support and updated bindings from
        Hongbo

      - msx-dma fixes and cleanup by Markus

   - DMAengine updates from Dan:

      - Bartlomiej and Dan finalized a rework of the dma address unmap
        implementation.

      - In the course of testing 1/ a collection of enhancements to
        dmatest fell out.  Notably basic performance statistics, and
        fixed / enhanced test control through new module parameters
        'run', 'wait', 'noverify', and 'verbose'.  Thanks to Andriy and
        Linus [Walleij] for their review.

      - Testing the raid related corner cases of 1/ triggered bugs in
        the recently added 16-source operation support in the ioatdma
        driver.

      - Some minor fixes / cleanups to mv_xor and ioatdma"
