Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

Pull MIPS updates from Ralf Baechle:
 "The MIPS bits for 3.8.  This also includes a bunch fixes that were
  sitting in the linux-mips.org git tree for a long time.  This pull
  request contains updates to several OCTEON drivers and the board
  support code for BCM47XX, BCM63XX, XLP, XLR, XLS, lantiq, Loongson1B,
  updates to the SSB bus support, MIPS kexec code and adds support for
  kdump.

  When pulling this, there are two expected merge conflicts in
  include/linux/bcma/bcma_driver_chipcommon.h which are trivial to
  resolve, just remove the conflict markers and keep both alternatives."

  MIPS: MT: Fix build with CONFIG_UIDGID_STRICT_TYPE_CHECKS=y
  MIPS: Remove unused smvp.h
  MIPS/EDAC: Improve OCTEON EDAC support.
  MIPS: OCTEON: Add definitions for OCTEON memory contoller registers.
  MIPS: OCTEON: Add OCTEON family definitions to octeon-model.h
