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" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (139 commits) MIPS: jz4740: remove unnecessary null test before debugfs_remove MIPS: Octeon: remove unnecessary null test before debugfs_remove_recursive MIPS: ZBOOT: implement stack protector in compressed boot phase MIPS: mipsreg: remove duplicate MIPS_CONF4_FTLBSETS_SHIFT MIPS: Bonito64: remove a duplicate define MIPS: Malta: initialise MAARs MIPS: Initialise MAARs MIPS: detect presence of MAARs MIPS: define MAAR register accessors & bits MIPS: mark MSA experimental MIPS: Don't build MSA support unless it can be used MIPS: consistently clear MSA flags when starting & copying threads MIPS: 16 byte align MSA vector context MIPS: disable preemption whilst initialising MSA MIPS: ensure MSA gets disabled during boot MIPS: fix read_msa_* & write_msa_* functions on non-MSA toolchains MIPS: fix MSA context for tasks which don't use FP first MIPS: init upper 64b of vector registers when MSA is first used MIPS: save/disable MSA in lose_fpu MIPS: preserve scalar FP CSR when switching vector context ...
