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 4.3 for MIPS. Here's the summary: Three fixes that didn't make 4.2-stable: - a -Os build might compile the kernel using the MIPS16 instruction set but the R2 optimized inline functions in <uapi/asm/swab.h> are implemented using 32-bit wide instructions which is invalid. - a build error in pgtable-bits.h for a particular kernel configuration. - accessing registers of the CM GCR might have been compiled to use 64 bit accesses but these registers are onl 32 bit wide. And also a few new bits: - move the ATH79 GPIO driver to drivers/gpio - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h, change ATH79 accordingly. - fix definition of pgprot_writecombine - add an implementation of dma_map_ops.mmap - fix alignment of quiet build output for vmlinuz link - BCM47xx: Use kmemdup rather than duplicating its implementation - Netlogic: Fix 0x0x prefixes of constants. - merge Bjorn Helgaas' series to remove most of the weak keywords from function declarations. - CP0 and CP1 registers are best considered treated as unsigned values to avoid large values from becoming negative values. - improve support for the MIPS GIC timer. - enable common clock framework for Malta and SEAD3. - a number of improvments and fixes to dump_tlb(). - document the MIPS TLB dump functionality in Magic SysRq. - Cavium Octeon CN68XX improvments. - NetLogic improvments. - irq: Use access helper irq_data_get_affinity_mask. - handle MSA unaligned accesses. - a number of R6-related math-emu fixes. - support for I6400. - improvments to MSA support. - add uprobes support. - move from deprecated __initcall to arch_initcall. - remove finish_arch_switch(). - IRQ cleanups by Thomas Gleixner. - migrate to new 'set-state' interface. - random small cleanups" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (148 commits) MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16. MIPS: Fix alignment of quiet build output for vmlinuz link MIPS: math-emu: Remove unused handle_dsemul function declaration MIPS: math-emu: Add support for the MIPS R6 MAX{, A} FPU instruction MIPS: math-emu: Add support for the MIPS R6 MIN{, A} FPU instruction MIPS: math-emu: Add support for the MIPS R6 CLASS FPU instruction MIPS: math-emu: Add support for the MIPS R6 RINT FPU instruction MIPS: math-emu: Add support for the MIPS R6 MSUBF FPU instruction MIPS: math-emu: Add support for the MIPS R6 MADDF FPU instruction MIPS: math-emu: Add support for the MIPS R6 SELNEZ FPU instruction MIPS: math-emu: Add support for the MIPS R6 SELEQZ FPU instruction MIPS: math-emu: Add support for the CMP.condn.fmt R6 instruction MIPS: inst.h: Add new MIPS R6 FPU opcodes MIPS: Octeon: Fix management port MII address on Kontron S1901 MIPS: BCM47xx: Use kmemdup rather than duplicating its implementation STAGING: Octeon: Use common helpers for determining interface and port MIPS: Octeon: Support interfaces 4 and 5 MIPS: Octeon: Set up 1:1 mapping between CN68XX PKO queues and ports MIPS: Octeon: Initialize CN68XX PKO STAGING: Octeon: Support CN68XX style WQE ...
