Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"This is the main pull request for 3.17. It contains:
- misc Cavium Octeon, BCM47xx, BCM63xx and Alchemy updates
- MIPS ptrace updates and cleanups
- various fixes that will also go to -stable
- a number of cleanups and small non-critical fixes.
- NUMA support for the Loongson 3.
- more support for MSA
- support for MAAR
- various FP enhancements and fixes"
