Merge tag 'mips_4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips

Pull MIPS updates from James Hogan:
 "Here's the main MIPS pull request for 4.11.

  It contains a few new features such as IRQ stacks, cacheinfo support,
  and KASLR for Octeon CPUs, and a variety of smaller improvements and
  fixes including devicetree additions, kexec cleanups, microMIPS stack
  unwinding fixes, and a bunch of build fixes to clean up continuous
  integration builds.

  Its all been in linux-next for at least a couple of days, most of it
  far longer.

  Miscellaneous:
   - Add IRQ stacks
   - Add cacheinfo support
   - Add "uzImage.bin" zboot target
   - Unify performance counter definitions
   - Export various (mainly assembly) symbols alongside their
     definitions
   - Audit and remove unnecessary uses of module.h

  kexec & kdump:
   - Lots of improvements and fixes
   - Add correct copy_regs implementations
   - Add debug logging of new kernel information

  Security:
   - Use Makefile.postlink to insert relocations into vmlinux
   - Provide plat_post_relocation hook (used for Octeon KASLR)
   - Add support for tuning mmap randomisation
   - Relocate DTB

  microMIPS:
   - A load of unwind fixes
   - Add some missing .insn to fix link errors

  MIPSr6:
   - Fix MULTU/MADDU/MSUBU sign extension in r2 emulation
   - Remove r2_emul_return and use ERETNC unconditionally on MIPSr6
   - Allow pre-r6 emulation on SMP MIPSr6 kernels

  Cache management:
   - Treat physically indexed dcache as non-aliasing
   - Add return errors to protected cache ops for KVM
   - CM3: Ensure L1 & L2 cache ECC checking matches
   - CM3: Indicate inclusive caches
   - I6400: Treat dcache as physically indexed

  Memory management:
   - Ensure bootmem doesn't corrupt reserved memory
   - Export some TLB exception generation functions for KVM

  OF:
   - NULL check initial_boot_params before use in of_scan_flat_dt()
   - Fix unaligned access in of_alias_scan()

  SMP:
   - CPS: Don't BUG if a CPU fails to start

  Other fixes:
   - Fix longstanding 64-bit IP checksum carry bug
   - Fix KERN_CONT fallout in cpu-bugs64.c and sync-r4k.c
   - Update defconfigs for NF_CT_PROTO_DCCP, DPLITE,
     CPU_FREQ_STAT,SCSI_DH changes
   - Disable certain builtin compiler options, stack-check (whole
     kernel), asynchronous-unwind-tables (VDSO).
   - A bunch of build fixes from kernelci.org testing
   - Various other minor cleanups & corrections

  BMIPS:
   - Migrate interrupts during bmips_cpu_disable
   - BCM47xx: Add Luxul devices

   - Fix cascading IRQ setup
   - Fix build of VPE loader
   - xway: Fix ethernet packet header corruption over reboot

  Loongson1
   - Add watchdog support
   - 1B: Reduce DEFAULT_MEMSIZE to 64MB
   - 1B: Change OSC clock name to match rest of kernel
   - 1C: Remove ARCH_WANT_OPTIONAL_GPIOLIB

  Octeon:
   - Add KASLR support
   - Support Octeon III USB controller
   - Fix large copy_from_user corner case
   - Enable devtmpfs in defconfig

   - Fix non-default XLR build error due to netlogic,xlp-pic code
   - Fix assembler warning from smpboot.S

  pic32mzda:
   - Fix linker error when early printk is disabled

  Pistachio:
   - Add base device tree
   - Add Ci40 "Marduk" device tree

  Ralink:
   - Support raw appended DTB
   - Add missing I2C & I2S clocks
   - Add missing pinmux and fix pinmux function name typo
   - Add missing clk_round_rate()
   - Clean up prom_init()
   - MT7621: Set SoC type
   - MT7621: Support highmem

  TXx9:
   - Modernize printing of kernel messages and resolve KERN_CONT fallout
   - 7segled: use permission-specific DEVICE_ATTR variants

  XilFPGA:
   - Add IRQ controller and UART IRQ
   - Add AXI I2C and emaclite to DT & defconfig"
