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."
