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"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (124 commits)
MIPS: Kconfig: Add missing MODULES dependency to VPE_LOADER
MIPS: BCM63xx: CLK: Add dummy clk_{set,round}_rate() functions
MIPS: SEAD3: Disable L2 cache on SEAD-3.

MIPS: BCM63xx: Add SMP support to prom.c
MIPS: define write{b,w,l,q}_relaxed
MIPS: Expose missing pci_io{map,unmap} declarations
MIPS: Malta: Update GCMP detection.
Revert "MIPS: make CAC_ADDR and UNCAC_ADDR account for PHYS_OFFSET"
MIPS: APSP: Remove <asm/kspd.h>
SSB: Kconfig: Amend SSB_EMBEDDED dependencies
MIPS: microMIPS: Fix improper definition of ISA exception bit.
MIPS: Don't try to decode microMIPS branch instructions where they cannot exist.
MIPS: Declare emulate_load_store_microMIPS as a static function.
MIPS: Fix typos and cleanup comment
MIPS: Cleanup indentation and whitespace
MIPS: BMIPS: support booting from physical CPU other than 0
MIPS: Only set cpu_has_mmips if SYS_SUPPORTS_MICROMIPS
MIPS: GIC: Fix gic_set_affinity infinite loop
MIPS: Don't save/restore OCTEON wide multiplier state on syscalls.
