Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"MIPS updates:
- All the things that didn't make 3.10.
- Removes the Windriver PPMC platform. Nobody will miss it.
- Remove a workaround from kernel/irq/irqdomain.c which was there
exclusivly for MIPS. Patch by Grant Likely.
- More small improvments for the SEAD 3 platform
- Improvments on the BMIPS / SMP support for the BCM63xx series.
- Various cleanups of dead leftovers.
- Platform support for the Cavium Octeon-based EdgeRouter Lite.
Two large KVM patchsets didn't make it for this pull request because
their respective authors are vacationing"
