Pull MIPS updates from Paul Burton: - Support for the MIPSr6 MemoryMapID register & Global INValidate TLB (GINVT) instructions, allowing for more efficient TLB maintenance when running on a CPU such as the I6500 that supports these. - Enable huge page support for MIPS64r6. - Optimize post-DMA cache sync by removing that code entirely for kernel configurations in which we know it won't be needed. - The number of pages allocated for interrupt stacks is now calculated correctly, where before we would wastefully allocate too much memory in some configurations. - The ath79 platform migrates to devicetree. - The bcm47xx platform sees fixes for the Buffalo WHR-G54S board. - The ingenic/jz4740 platform gains support for appended devicetrees. - The cavium_octeon, lantiq, loongson32 & sgi-ip27 platforms all see cleanups as do various pieces of core architecture code. * tag 'mips_5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (66 commits) MIPS: lantiq: Remove separate GPHY Firmware loader MIPS: ingenic: Add support for appended devicetree MIPS: SGI-IP27: rework HUB interrupts MIPS: SGI-IP27: do boot CPU init later MIPS: SGI-IP27: do xtalk scanning later MIPS: SGI-IP27: use pr_info/pr_emerg and pr_cont to fix output MIPS: SGI-IP27: clean up bridge access and header files MIPS: SGI-IP27: get rid of volatile and hubreg_t MIPS: irq: Allocate accurate order pages for irq stack MIPS: dma-noncoherent: Remove bogus condition in dma_sync_phys() MIPS: eBPF: Remove REG_32BIT_ZERO_EX MIPS: eBPF: Always return sign extended 32b values MIPS: CM: Fix indentation MIPS: BCM47XX: Fix/improve Buffalo WHR-G54S support MIPS: OCTEON: program rx/tx-delay always from DT MIPS: OCTEON: delete board-specific link status MIPS: OCTEON: don't lie about interface type of CN3005 board MIPS: OCTEON: warn if deprecated link status is being used MIPS: OCTEON: add fixed-link nodes to in-kernel device tree MIPS: Delete unused flush_cache_sigtramp() ...

Merge tag 'y2038-syscall-abi' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground into timers/2038

Pull additional syscall ABI cleanup for y2038 from Arnd Bergmann: This is a follow-up to the y2038 syscall patches already merged in the tip tree. As the final 32-bit RISC-V syscall ABI is still being decided on, this is the last chance to make a few corrections to leave out interfaces based on 32-bit time_t along with the old off_t and rlimit types. The series achieves this in a few steps: - A couple of bug fixes for minor regressions I introduced in the original series - A couple of older patches from Yury Norov that I had never merged in the past, these fix up the openat/open_by_handle_at and getrlimit/setrlimit syscalls to disallow the old versions of off_t and rlimit. - Hiding the deprecated system calls behind an #ifdef in include/uapi/asm-generic/unistd.h - Change arch/riscv to drop all these ABIs. Originally, the plan was to also leave these out on C-Sky, but that now has a glibc port that uses the older interfaces, so we need to leave them in place.

MIPS: ingenic: Add support for appended devicetree

dma-mapping: improve selection of dma_declare_coherent availability

2019-02-20T14:26:35Z

This API is primarily used through DT entries, but two architectures and two drivers call it directly. So instead of selecting the config symbol for random architectures pull it in implicitly for the actual users. Also rename the Kconfig option to describe the feature better.

MIPS: SGI-IP27: rework HUB interrupts

2019-02-19T20:46:03Z

This commit rearranges the HUB interrupt code by using MIPS_IRQ_CPU interrupt handling code and modern Linux IRQ framework features to get rid of global arrays. It also adds support for irq affinity setting.

32-bit userspace ABI: introduce ARCH_32BIT_OFF_T config option

2019-02-19T09:10:05Z

All new 32-bit architectures should have 64-bit userspace off_t type, but existing architectures has 32-bit ones. To enforce the rule, new config option is added to arch/Kconfig that defaults ARCH_32BIT_OFF_T to be disabled for new 32-bit architectures. All existing 32-bit architectures enable it explicitly. New option affects force_o_largefile() behaviour. Namely, if userspace off_t is 64-bits long, we have no reason to reject user to open big files. Note that even if architectures has only 64-bit off_t in the kernel (arc, c6x, h8300, hexagon, nios2, openrisc, and unicore32), a libc may use 32-bit off_t, and therefore want to limit the file size to 4GB unless specified differently in the open flags.

MIPS: Loongson32: Fix config brokenness; select SYS_SUPPORTS_32BIT_KERNEL

2019-02-04T22:44:06Z

Commit a96d68ba3b41 ("MIPS: Loongson32: clarify we don't support MIPS16 and merge configs") attempted to reduce duplication in Kconfig by consolidating some selects common to Loongson 1B & 1C CPUs under CPU_LOONGSON1. Unfortunately it clearly wasn't tested because by removing SYS_SUPPORTS_32BIT_KERNEL it prevented 32BIT from being enabled leading to all sorts of strange build errors from a kernel configured to build as neither 32 nor 64 bit. Both loongson1b_defconfig & loongson1c_defconfig failed to build due to this problem. Revert the cleanup portions of commit a96d68ba3b41 ("MIPS: Loongson32: clarify we don't support MIPS16 and merge configs"), keeping only its removal of the selection of SYS_SUPPORTS_MIPS16.
