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" * tag 'mips_4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips: (148 commits) MIPS: VDSO: Explicitly use -fno-asynchronous-unwind-tables MIPS: BCM47XX: Fix button inversion for Asus WL-500W MIPS: DTS: Add img directory to Makefile MIPS: ip27: Disable qlge driver in defconfig MIPS: pic32mzda: Fix linker error for pic32_get_pbclk() MIPS: Lantiq: Keep ethernet enabled during boot MIPS: OCTEON: Fix copy_from_user fault handling for large buffers MIPS: Fix special case in 64 bit IP checksumming.

MIPS: ip27: Disable qlge driver in defconfig

2017-02-17T11:14:30Z

One of the last remaining failures in kernelci.org is for a gcc bug: drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: error: insn does not satisfy its constraints: drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: internal compiler error: in extract_constrain_insn, at recog.c:2190 This is apparently broken in gcc-6 but fixed in gcc-7, and I cannot reproduce the problem here. However, it is clear that ip27_defconfig does not actually need this driver as the platform has only PCI-X but not PCIe, and the qlge adapter in turn is PCIe-only. The driver was originally enabled in 2010 along with lots of other drivers. Fixes: 59d302b342e5 ("MIPS: IP27: Make defconfig useful again.")

MIPS: OCTEON: Enable DEVTMPFS

2017-02-15T18:45:06Z

Recent versions of udev and systemd require the kernel to be compiled with CONFIG_DEVTMPFS in order to populate the /dev directory. Most MIPS platforms have it enabled by default, so enable it for the Cavium Octeon defconfig as well. This will assist with automated kernel boot testing.

cpufreq: Remove CONFIG_CPU_FREQ_STAT_DETAILS config option

2017-02-03T22:59:39Z

This doesn't have any benefit apart from saving a small amount of memory when it is disabled. The ifdef hackery in the code makes it dirty unnecessarily. Clean it up by removing the Kconfig option completely. Few defconfigs are also updated and CONFIG_CPU_FREQ_STAT_DETAILS is replaced with CONFIG_CPU_FREQ_STAT now in them, as users wanted stats to be enabled.

MIPS: Update ip27_defconfig for SCSI_DH change

MIPS: Update defconfigs for NF_CT_PROTO_DCCP/UDPLITE change

2017-01-24T17:30:34Z

In linux-4.10-rc, NF_CT_PROTO_UDPLITE and NF_CT_PROTO_DCCP are bool symbols instead of tristate, and kernelci.org reports a bunch of warnings for this, like: arch/mips/configs/malta_kvm_guest_defconfig:63:warning: symbol value 'm' invalid for NF_CT_PROTO_UDPLITE arch/mips/configs/malta_defconfig:62:warning: symbol value 'm' invalid for NF_CT_PROTO_DCCP arch/mips/configs/malta_defconfig:63:warning: symbol value 'm' invalid for NF_CT_PROTO_UDPLITE arch/mips/configs/ip22_defconfig:70:warning: symbol value 'm' invalid for NF_CT_PROTO_DCCP arch/mips/configs/ip22_defconfig:71:warning: symbol value 'm' invalid for NF_CT_PROTO_UDPLITE This changes all the MIPS defconfigs with these symbols to have them built-in.
