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
- BCM47xx: Fix Asus WL-500W button inversion
- BCM7xxx: Add SPI device nodes
Generic (multiplatform):
- Add kexec DTB passing
- Fix big endian
- Add cpp_its_S in ksym_dep_filter to silence build warning
IP22:
- Reformat inline assembler code to modern standards
- Fix binutils 2.25 build error
IP27:
- Fix duplicate CAC_BASE definition build error
- Disable qlge driver to workaround broken compiler
Lantiq:
- Refresh defconfig and activate more drivers
- Lock DMA register access
- 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
Netlogic:
- 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"
