Pull MIPS updates from Ralf Baechle:
 - three fixes for 3.15 that didn't make it in time
 - limited Octeon 3 support.
 - paravirtualization support
 - improvment to platform support for Netlogix SOCs.
 - add support for powering down the Malta eval board in software
 - add many instructions to the in-kernel microassembler.

e1b77baed6 mips: xlp: copy built-in DTB out of init section
The existing code is buggy because built-in DTBs are in init memory.
It is also broken because the reserved bootmem was then freed after
unflattening, but the unflattened tree points to data in the flat tree.
Fix this by using the unflatten_and_copy_device_tree function.

This removes all accesses to FDT header data by the arch code.

Linus Torvalds
cdfc83075f Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
 "The most notable new addition inside this pull request is the support
  for MIPS's latest and greatest core called "inter/proAptiv".  The
  patch series describes this core as follows.

    "The interAptiv is a power-efficient multi-core microprocessor
     for use in system-on-chip (SoC) applications. The interAptiv combines
     a multi-threading pipeline with a coherence manager to deliver improved
     computational throughput and power efficiency. The interAptiv can
     contain one to four MIPS32R3 interAptiv cores, system level
     coherence manager with L2 cache, optional coherent I/O port,
     and optional floating point unit."

  The platform specific patches touch all 3 Broadcom families.  It adds
  support for the new Broadcom/Netlogix XLP9xx Soc, building a common
  BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count
  and full gpio button/led descriptions for BCM47xx.

  The rest of the series are cleanups and bug fixes that are MIPS
  generic and consist largely of changes that Imgtec/MIPS had published
  in their linux-mti-3.10.git stable tree.  Random other cleanups and
  patches preparing code to be merged in 3.15"

c24a8a7a99 MIPS: Netlogic: Add MSI support for XLP
Add MSI chip and MSIX chip definitions.

For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.

The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.

For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.

The MSI-X chip definition uses the standard functions to enable
and disable interrupts.

10d0c9705e DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.
 
 - Cross arch clean-up and consolidation of early DT scanning code.
 - Clean-up and removal of arch prom.h headers. Makes arch specific
   prom.h optional on all but Sparc.
 - Addition of interrupts-extended property for devices connected to
   multiple interrupt controllers.
 - Refactoring of DT interrupt parsing code in preparation for deferred
   probe of interrupts.
 - ARM cpu and cpu topology bindings documentation.
 - Various DT vendor binding documentation updates.

e363bbac31 MIPS: Netlogic: replace early_init_devtree() call
The early_init_devtree() API was removed in linux-next for 3.13 with
commit "mips: use early_init_dt_scan". This causes Netlogic XLP compile
to fail:

arch/mips/netlogic/xlp/setup.c:101: undefined reference to `early_init_devtree'

Add xlp_early_init_devtree() which uses the __dt_setup_arch() to
handle early device tree related initialization to fix this.
