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"
