Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle: "This is the first round of fixes and tying up loose ends for MIPS. - plenty of fixes for build errors in specific obscure configurations - remove redundant code on the Lantiq platform - removal of a useless SEAD I2C driver that was causing a build issue - fix an earlier TLB exeption handler fix to also work on Octeon. - fix ISA level dependencies in FPU emulator's instruction decoding. - don't hardcode kernel command line in Octeon software emulator. - fix an earlier fix for the Loondson 2 clock setting" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: SEAD3: Fix I2C device registration. MIPS: SEAD3: Nuke PIC32 I2C driver. MIPS: ftrace: Fix a microMIPS build problem MIPS: MSP71xx: Fix build error MIPS: Malta: Do not build the malta-amon.c file if CMP is not enabled MIPS: Prevent compiler warning from cop2_{save,restore} MIPS: Kconfig: Add missing MIPS_CPS dependencies to PM and cpuidle MIPS: idle: Remove leftover __pastwait symbol and its references MIPS: Sibyte: Include the swarm subdir to the sb1250 LittleSur builds MIPS: ptrace.h: Add a missing include MIPS: ath79: Fix compilation error when CONFIG_PCI is disabled MIPS: MSP71xx: Remove compilation error when CONFIG_MIPS_MT is present MIPS: Octeon: Remove special case for simulator command line. MIPS: tlbex: Properly fix HUGE TLB Refill exception handler MIPS: loongson2_cpufreq: Fix CPU clock rate setting mismerge pci: pci-lantiq: remove duplicate check on resource MIPS: Lasat: Add missing CONFIG_PROC_FS dependency to PICVUE_PROC MIPS: cp1emu: Fix ISA restrictions for cop1x_op instructions
