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 deprecated. There is no need to check for it in device
driver code and no need to specify it in the device tree. Remove the
property from stock .dts files and remove the check for it from device
drivers. This change should be 100% backwards compatible with old device
trees.

device_type is a deprecated property, but some MDIO bus nodes still have
it. Except for a couple of old binding (compatible="gianfar" and
compatible="ucc_geth_phy") the kernel doesn't look for
device_type="mdio" at all.

This patch removes all instances of device_type="mdio" from the binding
documentation and the .dts files.

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.

sed -i '/"ethernet-phy"/d' `git grep -l '"ethernet-phy"'`

this addresses the clock driver aka provider's side of clocks
- introduce a 'clocks' subtree with an 'osc' node for the crystal
  or oscillator SoC input (fixed frequency)
- the 'clock@f00' clock-control-module node references the 'osc' for
  its input, and is another provider for all the clocks which the
  CCM component manages
- prepare for future references to clocks from peripheral nodes
  by means of the <&clks ID> syntax and symbolic ID names which a
  header file provides
- provide default values with 33MHz oscillator frequency in the
  common include (the 66MHz IPS bus already was there), and add
  override values for the ifm AC14xx board which deviates from
  the reference design (25MHz xtal, 80MHz IPS bus)

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.

Only build board support files when required.") the two defconfigs
ep88xc_defconfig and storcenter_defconfig would fail final link as
follows:
