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"
