Merge tag 'mips_5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS changes from Paul Burton: "Nothing too big or scary in here: - Support mremap() for the VDSO, primarily to allow CRIU to restore the VDSO to its checkpointed location. - Restore the MIPS32 cBPF JIT, after having reverted the enablement of the eBPF JIT for MIPS32 systems in the 5.5 cycle. - Improve cop0 counter synchronization behaviour whilst onlining CPUs by running with interrupts disabled. - Better match FPU behaviour when emulating multiply-accumulate instructions on pre-r6 systems that implement IEEE754-2008 style MACs. - Loongson64 kernels now build using the MIPS64r2 ISA, allowing them to take advantage of instructions introduced by r2. - Support for the Ingenic X1000 SoC & the really nice little CU Neo development board that's using it. - Support for WMAC on GARDENA Smart Gateway devices. - Lots of cleanup & refactoring of SGI IP27 (Origin 2*) support in preparation for introducing IP35 (Origin 3*) support. - Various Kconfig & Makefile cleanups" * tag 'mips_5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (60 commits) MIPS: PCI: Add detection of IOC3 on IO7, IO8, IO9 and Fuel MIPS: Loongson64: Disable exec hazard MIPS: Loongson64: Bump ISA level to MIPSR2 MIPS: Make DIEI support as a config option MIPS: OCTEON: octeon-irq: fix spelling mistake "to" -> "too" MIPS: asm: local: add barriers for Loongson MIPS: Loongson64: Select mac2008 only feature MIPS: Add MAC2008 Support Revert "MIPS: Add custom serial.h with BASE_BAUD override for generic kernel" MIPS: sort MIPS and MIPS_GENERIC Kconfig selects alphabetically (again) MIPS: make CPU_HAS_LOAD_STORE_LR opt-out MIPS: generic: don't unconditionally select PINCTRL MIPS: don't explicitly select LIBFDT in Kconfig MIPS: sync-r4k: do slave counter synchronization with disabled HW interrupts MIPS: SGI-IP30: Check for valid pointer before using it MIPS: syscalls: fix indentation of the 'SYSNR' message MIPS: boot: fix typo in 'vmlinux.lzma.its' target MIPS: fix indentation of the 'RELOCS' message dt-bindings: Document loongson vendor-prefix MIPS: CU1000-Neo: Refresh defconfig to support HWMON and WiFi. ...
