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: Enable second core SMP on BCM6328 if available 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. ...
